二迭体

Past investigation found the rock in the right dam foundation composing of granite(γ_4~3～γ_5~1) in dyas- trias,which has a very complicated mechanical environment. The complicated phenomenon is as follows: tectonism, alteration, rock mass demobilize, rock mass stress release and other factors.

前期的调查表明其右岸岩体力学环境复杂，表现为：构成右岸坝基岩体主体的二迭～三迭纪花岗岩(γ_4~3～γ_5~1)受构造变动、蚀变、风化卸荷等因素的影响形成了坝基软弱岩带和坝肩上部卸荷松弛岩体。

Iterative method of integral equation is used to solve electromagnetic scattering from multiple conducting cylinders in this paper.

In the Triassic-early Jurassic, the emplacement mechanism of monzonitic granite and orthoclase granite is dominated by tectonic extension and the diapirism is strong. The strong balloon swelling is dominant and tectonic extension is subordinate during the emplacement mechanism of early Jurassic alkali granite.

晚三迭世－早侏罗世二长、正长花岗岩体就位过程中构造扩展机制起主导作用，岩浆底辟作用也较强；早侏罗世碱性花岗岩体岩浆就位过程中以强力的气球膨胀作用为主，构造扩展机制为辅。

Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Per-mo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ^34 S values of the ores commonly fall within the accepted mantle range of 0±2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ^34 S value is also within this range.

如1.1 Ga的Duluth杂岩、Noril'sk地区二迭－三迭纪侵入岩和1.4 Ga的Kabanga侵入岩体中矿床的硫同位素测定结果证明硫来自含硫化物和硫酸盐的围岩。1.3 Ga的Voisbey's Bay矿床矿石的硫同位素δ^34 S值通常落入公认的地幔硫同位素组成范围(0±2‰)内，而对其元古宙变质沉积围岩进行的详细研究结果显示δ^34 S的平均值也在此范围。
