Volcanism in Cameroon happens principally on the Cameroon Volcanic Line (CVL), with the biggest and most dynamic spring of gushing lava being Mount Cameroon (Fitton, 1980). The CVL, speaking to soluble volcanoes, demonstrates a simple unmistakable Y-shape, with volcanic focuses in both the maritime and mainland areas of the African plate (Fitton and Dunlop, 1985). Agreement with respect to the main thrusts of these volcanoes still can't seem to be come to. Be that as it may, a wide assortment of speculations and theories tending to the root and nature of the CVL have been distributed in the course of the most recent couple of decades. The CVL is a 1600km long magmatic grouping, extending from Pagalu Island in the Gulf of Guinea (Atlantic Ocean) to Lank Chad on the primary place where there is Cameroon on the western African landmass (Déruelle, Ngounouno and Demaiffe, 2007). Geologically the CVL is arranged relatively parallel to the Benue Trough, and takes after the length of the Ngaoundéré Fault (Ballentine, Lee and Halliday, 1997). The northern appendage of the CVL covers with the Chad crack, which denotes the northern break of the Benue Trough (Fitton, 1980). Despite the fact that volcanism is as yet dynamic along the CVL is it not a neogene highlight and has been dynamic since the start of the Tertiary time frame. The stones from the CVL are delegated essentially antacid, middle of the road and felsic. The felsic and basaltic magmas increment inlands towards the branches of the CVL in a volumetric proportion (Déruelle, Ngounouno and Demaiffe, 2007). One of Africa's biggest volcanoes, Mount Cameroon, is a volcanic horst, with an inexact tallness of 4075m. The abundance of Mount Cameroon is the most dynamic spring of gushing lava on the CVL. The most recent emission of Mount Cameroon was in the year 2000 (Herrero-Bervera et al. 2004). Researchers attempted different techniques throughout the years trying to elucidate the inception and progression of the CVL. Amid the 1980's Fitton (1980) proposed a basic model to clarify the land highlights of the CVL. Fitton (1980) noticed that in spite of the fact that there is no proof for fracture blaming there are indications of territorial elevate of the bowl. The mainland segment of the CVL is portrayed by strato-volcanoes (Mount Cameroon), focal volcanic massifs and even calderas in a few territories. Fell fields filled by silt, single attractive volcanoes and surge basalts ( Ngaoundéré Plateau) are additionally noticeable on the mainland segment (Nkouathio et al. 2008). The volcanism isn't affected by cracks, which existed before the volcanism in the cellar (Fitton, 1980). The inception of the CVL is clarified by hand of the striking connection between the CVL and the Benue Trough highlights. Fitton (1980) proposed that the CVL and the Benue Trough are superimposed by pivoting one component by 7° in connection to the next, around a hub. The pivot is portrayed to keep running with a north eastern strike into the nation of Sudan. The purpose behind the relative revolution of the CVL and the Benue Trough is estimated to be because of the clockwise pivot of Africa (ca. 80Ma – 65Ma) (Fitton, 1980). This clockwise pivot may give confirmation to three highlights. Right off the bat, on the starting point, the size and Y-formed geometry of the CVL, furthermore the pivot may bolster purpose behind the nonattendance of ongoing volcanism in the Benue Trough. Thirdly, the rotational hypothesis may give confirmation to the collapsing of the Benue Trough residue. There were a few theories that the volcanism by and by dynamic in the CVL was once dynamic in the Benue Trough. On the off chance that the volcanic line had moved from the Benue Though to its present position a methodical relocation of a problem area is inferred. Ngako et al. (2006) utilized remote detecting information as proposed by Moreau et al. (1987) to propose that the connection between push administrations and intraplate antacid magmatism in the CVL is controlled by lithospheric structures. Ubangoh et al. (2005) contended that the nearness of various late volcanic cones and holes along the CVL means that a solid geothermal inclination underneath the volcanic line, in spite of the fact that there are no information that demonstrates an expanded supply of warmth. By utilizing a geochemical ponder on the basaltic rocks of the CVL and a K-Ar dating project, Fitton and Dunlop (1985) hunt down confirmation to demonstrate a precise movement of the CVL volcanoes. Since the CVL is arranged in such a remarkable topographical setting, Fitton and Dunlop (1985) contemplated that they can decide the wellspring of the CVL magmas by looking at the isotopic proportions of salt basalts on the maritime part with the isotopic information of the soluble base basalts on the mainland segment of the volcanic line. Fitton and Dunlop have discovered that both the significant component structures and additionally the isotopic proportions are undefined when looking at the maritime and mainland parts. What the K-Ar information proved was that numerous volcanoes were dynamic along the line in pretty much a similar day and age. Whenever Ballentine, Lee and Halliday (1997) analyzed the periods of the maritime part volcanoes, they found that there is a consistency between the revolution of the Cretaceous African plate (Fitton, 1980) and the times of the prior uncovered shakes on the islands. The periods of the early uncovered magmas diminish from the mainland side towards the sea, putting Principe at 31Ma and Pagalu at 4.8Ma. The efficient age decline of the islands bolster the mantle crest demonstrate for the maritime area of the CVL, however does exclude the mainland part. Different reasons for volcanism, for example, crack blaming and previous storm cellar breaks were at first disposed of because of inability to gather strong confirmation. The volcanoes on the sea floor demonstrated no progressions because of the shortcomings they goes through, in this manner one can accept that the wellspring of these volcanoes are from mantle forms and isn't influenced by structures happening in the hull (Fitton, 1980).Research in light of the age and science of the CVL basalts, showed that the CVL is a youthful fracture related with the Benue Trough as opposed to a problem area trail. The profundity at which a spring of gushing lava is tapping its magma can be dictated by the radioactive rot of helium isotopes in crustal shake (Aka, et al. 2003). Helium fills in as a geochemical tracer that could be utilized to explore the change of magma over some stretch of time. It is by and large acknowledged that sea island basalts (OIB) demonstrate an extensive variety of 3He/4He (Zindler and Hart, 1986) and that 3He/4He proportions from mid sea edge basalts (MORB) are uniform (Graham et al. 1992a). The 3He/4He proportion of the CVL ranges from 3.05Ra to 8.31Ra. Hotspots by and large have substantially higher 3He/4He proportions (Hilton et al. 1999). Otherwise known as et al. (2003) was the first to distinguish that the circulation of the 3He/4He proportions on the CVL could be because of spatial control, and recommended that the helium isotopic dissemination a basic normal for the CVL is. These discoveries are contended as demonstrate that the CVL volcanoes doesn't tap their material straightforwardly from hotspots. Otherwise known as et al. (2003) is additionally went down by work Fitton and Dunlop (1985) did on K-Ar dating and the consistency to the Pb-isotope demonstrate proposed by Halliday et al. (1990).The previously mentioned information and the dependable volcanism of the CVL volcanoes bolsters the conclusion came to by Fitton and Dunlop (1985) that the magma driving the volcanoes on the mainland part couldn't begin from a profound mantle source. Subsequently the CVL demonstrates no confirmation of a mantle tuft in the mainland segment, yet rather marks convection of the upper mantle (Fitton and Dunlop, 1985). 206Pb/204Pb and 208Pb/204Pb isotope proportions demonstrated a slight reduction to either sides of the volcanic line from the focused fountain of liquid magma, Mt. Cameroon, which lies on the lithospheric mainland maritime limit (COB) (Ballentine, Lee and Halliday, 1997). Basalts from the COB volcanoes, for example, Mount Cameroon and Mount Etinde are more radiogenic with 206Pb/204Pb proportions of around 20.52 and 208Pb/204Pb proportions of 40.34 (Déruelle, Ngounouno and Demaiffe, 2007). The Pb proportions of the COB volcanoes demonstrate a solid differentiation to the lower radiogenic proportions of the island volcanoes. Basalts from the island situated far south from the COB, Pagalu Island, have the most reduced 206Pb/204Pb proportion of 19.01 and a 208Pb/204Pb proportion of 38.83. The Pb isotope information demonstrates that there happened no predictable significant change in the magma over some stretch of time. The Nd and Sr isotopes of the basalts from both the mainland and maritime areas are comparable in piece. The similarity of the geochemical and isotopic information amongst maritime and mainland basalts give confirm that the source and organization of the magma was not impacted by the mainland hull, and in this manner, the magma does not start from the lithosphere (Déruelle, Ngounouno and Demaiffe, 2007). The magma, as hypothesized by Ballentine, Lee and Halliday (1997), start from a sub-lithospheric source, in light of the comparative creations of the maritime and mainland magmas. Nkouathio et al. (2008) contended that since the magmas of the whole CVL have a shallow asthensopheric mantle source an exhausted MORB mantle and a metasomatosed mantle, the antacid magmas are predictable with the asthensopheric upwelling of a problem area. Halliday et al. (1990) contended that the isotopic abatements could derive re-liquefying of an enhanced mantle tuft situated underneath the COB. Halliday additionally contends that the crest conceivably moved (from its situation underneath the Benue Trough) to its present area amid the mainland separation between the African and South American plates and in addition the revolution of the cooler lithosphere in respect to the asthenosphere (Ballentine, Lee and Halliday, 1997). Ballentine, Lee and Halliday (1997) made it unmistakable that in spite of the fact that the isotopic information bolsters the mantle tuft hypothesis, the mantle crest is just a piece of the clarification of a more intricate volcanic setting. Itemized isotopic information exhibited that numerous hypotheses proposed in the past were excessively conflicting, making it impossible to clarify the beginning of the CVL.
