On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

The conception, studied objects and basic constituents of non-Smith strata are elaborated from theory level: Non-Smithian strata are the strata that have undergone mixing of different degrees, thus were deformed, metamorphosed and displaced into disorder totally or partially. They are the disorder parts in orogenic belts. Melange is the solo studied object of non- Smithian stratigraphy. The slices in melange is one of the basic constituents of non- Smithian strata, and also one of the basic units in the non-Smithian mapping. The slices used in this paper refer to blocks divided by small-scale tectonic boundaries and have certain constitutes. Superslices used in this paper refer to a set of slice association with similar tectonic deformation bounded by large-scale tectonic mixing.
从理论上阐述了非史密斯地层的概念、研究对象和基本构件:非史密斯地层(non-Smithian strata)是指那些经历过不同程度的混杂建造,并经历了变位,变形、变质,全部无序或部分无序的地层,主要指造山带地层中的无序部分;混杂岩是非史密斯地层的唯一研究对象;混杂岩中的构造岩片是非史密斯地层基本构件之一,亦是非史密斯地层和地质填图基本单位之一,岩片是指以构造拼合边界所分割的具有一定物质构成的地质体;物质建造形成于同一大的构造旋回期(如晋宁期、加里东期、海西期等)、亲源关系密切、大致经历了相似变形、变质历程的一套岩片组合体被称之为超岩片。
