Using computer-aided image processing to estimate chemical composition of igneous rocks: A potential tool for large-scale compositional mappingMappingImage processingColor calibrationGeochemistryDigital cameras, particularly on smartphones, have led to the proliferation of amateur photographers. Of interest ...
Obviously, the processes determining mineral composition of sandstones are more complex than simple mixing ones from source areas of different kinds. The discrepancy is great between observed and theoretically possible combinations of minerals.This is a preview of subscription content, log in via an ...
Each group contains rock samples which are also comparable with regard to their minearal composition. Each igneous rock association can be characterized by the percentage of chemical analyses which fall in each group. These numbers are very useful parameters in applying cluster analysis to the ...

What type of rock forms from the cooling of molten rock at or below the surface? Is it possible for 2 igneous rocks to have the same mineral composition but be different rocks? Mud cracks found in sedimentary rocks are evidence of deposition in an environment in which...
2) mineral chemical composition 矿物化学成分 1. Study on petrology and mineral chemical compositions of deep-derived mafic enclaves from high-K igneous rocks in Liuhe-Xiangduo area, eastern Tibet showed that the enclaves belong to metamorphic rocks formed in the mid-lower crust. 对青藏东缘...

Compositional and structural systematics of the columbite group The systematics of the columbite group have been studied to quantify variations in composition and structure. Multiple regression methods involving 89 heated samples and five synthetic equivalents of columbite-group minerals give equatio... TS...
