本文通过对攀枝花层状含矿岩体产生地质背景的详细研究以及据岩体中辉石单矿物^(40)Ar/^(89)Ar年龄(1508.8±5.17Ma),修正了前人对该岩体形成时代的认识;根据岩体的地质产状、岩石化学成分、微量元素特征与区内康定群中变质基性岩对... 本文通过对攀枝花层状含矿岩体产生地质背景的详细研究以及据岩体中辉石单矿物^(40)Ar/^(89)Ar年龄(1508.8±5.17Ma),修正了前人对该岩体形成时代的认识;根据岩体的地质产状、岩石化学成分、微量元素特征与区内康定群中变质基性岩对比,发现克拉通带范围内基性岩浆具有序列性演化规律,得出层状含矿岩体是区域基性岩浆演化的最终产物的结论;由于岩体韵律层构造具有施回性特点,提出基性岩浆多期多阶段成岩成矿作用的观点。这些认识将为区域矿产普查、评价提供有意义的基础资料。 展开更多

To seek new infinite sequence soliton-like exact solutions to nonlinear evolution equations (NEE(s)), by developing two characteristics of construction and mechanization on auxiliary equation method, the second kind of elliptie equation is highly studied and new type solutions and Backlund transformation are obtained. Then (2+ l )-dimensional breaking soliton equation is chosen as an example and its infinite sequence soliton-like exact solutions are constructed with the help of symbolic computation system Mathematica, which include infinite sequence smooth soliton-like solutions of Jacobi elliptic type, infinite sequence compact soliton solutions of Jacobi elliptic type and infinite sequence peak soliton solutions of exponential function type and triangular function type. 展开更多
