The development of magmatism along the Cameroon Volcanic Line: Evidence from teleseismic receiver functions

, 2012
[1] The Cameroon Volcanic Line (CVL) in West Africa is a chain of Cenozoic volcanism with no clear age progression. The reasons for its existence are unclear, and the nature of its magmatic plumbing system is poorly understood.

Genesis of the Xiaotazigou gold deposit in the northern margin of the north China craton: constraints from sulfur isotopes, rare earth elements, and trace elements

Frontiers in Earth Science
The Xiaotazigou gold deposit is located in the eastern section of the Chifeng–Chaoyang gold metallogenic belt on the northern margin of the North China Craton. In this study, rare earth and trace element compositions of ores and host rocks, together with

Petrologic-geochemical evidence of geologic-genetic uniformity of gold hydrothermal deposits formed in black-shale and non-shale substratum [PDF]

, 2007
The problem of gold deposits origin lying in crystal and black-shale substratum is discussed. The expediency of comparative research of all geologic-real-genetic factors of their formation, among which a significant value is retained by the geochemical ...

Late Middle to Late Ordovician Phosphate Accumulation of the Moyero River Section (Siberia): A Record of Upwelling and Global Cooling

Russian Journal of Earth Sciences
The phosphate-bearing rocks (phosphate rocks and phosphorites) were studied over a 45-meter interval of the Moyero river section, covering the upper part of the Darriwilian and the lower part of the Sandbian stages of the Ordovician.
