According to the variation in the components of intermediate-acid igneous rocks coming from the lower crust,it is possible to restrain the depth of the source area and the minimum thickness of the crust,and thus to provide important information for the study of the deep process of the continental intraplate mineralization.

A review of some achievements in research of xenoliths in granitoids in China and abroad has been made in this paper, with emphasis on the progresses in the studies of magmatic underplating, endogenetic mineralization, magmatic mixing, and regional metamorphism by use of xenoliths in granitoids.

Epithermal mineralization in the Western margin of the Luzon arc:Lalab gold deposit;

Initial discussion on geological characteristics of the Erbahuo silver deposit of Wengniute Inner Mongolia and its mineralization;

Hydrothermal mineralization of Au (Ag)-polymetallic ore deposit in the volcanic rock series of the Xiong'er Group;

Geological characteristics and metallogenesis of Sawayaerdun gold deposit in southwest Tianshan Mountains, Xinjiang;

The possible connection of the earth electric force and magnetic force controlling metallogenesis;

Post-orogenic dike complexes and implications for metallogenesis;

The Geologic, Geochemical Characteristics and Metallogeny of the Main Pb-Zn Deposits in South Tianshan Orogenic Belt;

Some fundamental problems of metallogeny are discussed on geodynamic bases.

Metallogeny of continents is an important research frontier in the contemporaneous metallogenic study, and its theoretical framework is conceived and established by gaining a deep knowledge and understanding of metallogeny in the continental collisional orogen.
