A comprehensive study of geochemistry was made on a series of the Jinning period (1. 0~0. 75Ga) igneous rocks from the Wudang region, South Qinling Orogenic belt (SQOB). It shows that the volcanics of Wudang Gp, aged ca. 1. 0-0. 95 Ga, have the affinitie
All igneous rocks form from the solidification of molten material, however, they can have very different appearances and characteristics depending upon the composition of the original material and where it cooled.

Guiana shield is located in the north of Amazon Craton, South America. Typical Archean granite-greenstone belt is developed extensively in the north part of Guiana shield. The rocks mainly include granite, gneiss, tonalite, Paleoproterozoic metamorphic ultrabasic-basic volcanic rock-intrusive rock and...

The most frequently encountered igneous rocks are granites, syenites, diorites, gabbros, diabases, basalts, trachytes, andesites, and porphyrites. The most widespread metamorphic rocks are gneisses, quartzites, siliceous shales, and marbles. The sedimentary rocks most frequently used to produce nono...
The first part is devoted to the theory of geosynclines in order to prepare the author and reader for the main discussion. The second part discusses the relationship of types of mineralization to types of igneous rocks, and also includes syngenetic deposits, and the relationship of ...
