In this paper we present a novel Point-based pattern analysis for predicting Cassiterite (tin-ore) as a secondary mineral deposit in the Plateau Younger Granite Region of Nigeria (PYGR) using statistics, spatial analysis and machine learning techniques. Existing mining data points collected from field survey in the PYGR and the geological map of the region were digitized and converted into shap...

the cu, pb, zn, ag-au deposit of amensif is located on the northern flank of the western high atlas. this deposit is hosted in lower cambrian carbonate bars and is structurally controlled by ne-sw to e-w trending fault structures and is spatially associated with the permian 273 ma azegour granite. ore reserves are around 0.5 mt and grades are 3.21% zn, 0.58% pb, 0.86% cu with 83.31 ppm ag and 0...

Submitted: Jul 19, 2013; Accepted: Sep 3, 2013; Published: Sep 11, 2013 Abstract: The study of isotopic ratios of oxygen and carbon has gained importance to determine the origin of ore bearing fluids, carbon origin and also to determine the formation temperature of non-sulfide lead and zinc minerals. In order to determine the origin of fluids and carbon existing in zinc carbonate minerals in Ch...

The Tuwu porphyry copper deposit is located on the Dananhu-Haerlik island arc in eastern Tianshan, NW China. Based geology, petrology, and situ trace element studies of pyrite chlorite, we redefined characteristics hydrothermal fluids following three mineralization stages: premineralization stage (stage Ⅰ), metallogenic Ⅱ), superimposed transformation Ⅲ). Pyrite Ⅰ (Py-I) has highest Co/Ni ratio...

Uranium (U) concentration and the activities of 238U, 234U, and 230Th were determined for groundwaters, spring waters, and lake water collected from the Shihongtan sandstone-hosted U ore district and in the surrounding area, NW China. The results show that the groundwaters from the oxidizing aquifer with high dissolved oxygen concentration (O2) and oxidation-reduction potential (Eh) are enriche...
