Mafic granulite and gabbro xenoliths are also found in the same kimberlitic pipes from the Eastern-North China platform, and suggest that multi-accretion events took place. The gabbro was formed lighly earlier with the host kimberlite. The underplating of the mafic magmas was related to the continental orogeny in the late middle-Ordovician Period.

The results showed compared with the native state the shear strength of rockmass under the saturation state decreased by 11.17%, cohesion force decreased by 16.09%, internal frictional angle decreased by 10.02%.(3) 3D-σFEM numerical simulation software is used to simulate the slope stability on the native state and saturation state. Compared with the nature state the displacement of the discontinuity and stress concentration in the saturation state is largened clearly, the results showed slope stability under the rainfall is weakened.
更多含有天然结构面的岩体试件进行了不同含水量下的强度试验,试验结果证明在岩体试件处于饱水状态时的结构面抗剪强度比天然状态下平均下降了11.17%、粘聚力平均下降了16.09%、内摩擦角平均下降了10.02%;(3)采用3D-σ有限元数值软件对K86+180~K86+470段岩质边坡进行了三维有限元数值模拟,并且分天然状态分阶段开挖和饱水状态分阶段开挖两种不同状况进行了稳定性分析,从分析结果可以看出与天然状态相比,饱水状态下软弱层水平方向位移明显增大,坡脚及软弱层特别是软弱层临空面附近的剪应力值显著增大,并且其安全系数与天然状态相比也显著减小,说明在有大的降雨发生当岩体处于饱水状态时边坡整体稳定性被削弱,边坡失稳可能性增大。

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓<1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓<0.5Ma, T〓A<850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.
