桐柏地区桐柏杂岩（CC）及地球化学特征

桐柏地区位于秦岭-桐柏-大别造山带的中段，是进行造山带东西构造关系研究的关键地区。现今桐柏山的构造样式是NWW-SEE向的一个短轴背彤构造，桐柏杂岩构成该短轴背彤构造的核部，主要岩石为花岗质片麻岩和斜长角闪岩，斜长角闪岩是早期的岩石，呈包体产出于晚期的花刚质片麻岩，局部可见早期岩石和晚期岩石搅和在一起，黑色条带强烈变形。两侧由高压变质单元组成。

Tongbai Complex Rocks and the Geochemical Characteristics in Tongbai Region

Tongbai region is located in the middle of the Qinling region - Tongbai-Dabie orogenic belt, which is the key areas of research of the relationship between tectonic belt. The structural style of the NWW-SEE in Tongbai mountain modern is a short back to the form structure. Parkinson complex form part of the short back-shaped core structure. The main rock is granitic gneiss and amphibolite, amphibolite rocks early, showing output in the late inclusion of the flowers just gneiss, and local rock shows that the early and late in the rock mix together with the strong deformation of the black bands on either side by high-pressure metamorphic units.
