| Abstract: | Since 1980s,such factors of continental lithosphere as its composition,texture,formation andevdution have become the forefront research field in geosciences,Orogenic belts seem to be thekey link in the study of continental lithosphere.Being an orogenic belt developed since Mesozoic,the Taihang Mountains-Yanshan orogenic belt is of great significance in studying the formation,devefopment and evolution of the crust in eastern China or even east Asia. As the lithomicroprobemethed is one of the simple and convenient methods in the study of deep geology , the authorshave discussed for the first time the influence of the composition of the upper mantle and the mid-dle-lower crust as well as the magmatic evolution upon the ore-forming process from the angle ofdioritoid enclaves. Preliminary studies have demonstrated that the tentative idea that dioritoid en-claves can serve as the lithomicroprobe of lithosphere to reflect the crust-mantle mineralization inorogenic belts is fairly reasonable. Hence, the idea provides a method for the study of orogenicbelts through the investigation into the crust-mantle evolution and mineralization. It is also point-ed out that mineralization and metallogeny of orogenic belts are controlled not only by regionalnonhomogeneity of the mantle,but obviously by the crust-mantle ore-forming system. The ratiosof metallogenic elements in dioritoid enclaves to those in the upper mantle and to those in themiddle-lower crust can reflect the metallogenic contribution of the upper mantle and that of themiddle-lower crust respectively. In addition,the ratios of metallogenic elements in granite to thosein dioritoid enclaves reflect the composite evolutionary results of granitic magma. |
