Regular tensile fractures develope in conglomerates of the young strata at the Sation trough , California,and the Arava Valley, Israel. The conglomerates are poorly cemented and matrix-supported. Tensile fractures are subparrallel to each other and mostly steep. They can be observed only in single Pebbles, not cutting through matrix. Regional trends of the tensile fractures are consistent with the orientations of the localhorizontal compression, which appear to be outcome under tectonic compression and...

Regular tensile fractures develope in conglomerates of the young strata at the Sation trough , California,and the Arava Valley, Israel. The conglomerates are poorly cemented and matrix-supported. Tensile fractures are subparrallel to each other and mostly steep. They can be observed only in single Pebbles, not cutting through matrix. Regional trends of the tensile fractures are consistent with the orientations of the localhorizontal compression, which appear to be outcome under tectonic compression and may be taken as good indicators of tectonic stresses. It can be used to tell the tectonic compression at the places poorly explored suchas the Northwestern China.

在加里福尼亚的萨尔顿地堑区和以色列阿拉瓦裂谷的较新地层中,具杂基支撑结构,胶结疏松的砾岩中的砾石内普遍发育规则的张裂缝系。张裂缝倾角大都很陡,彼此近于平行,且只在砾石内部发育,不切穿基质.张裂缝系的走向在区域上与当地的水平压应力方向吻合良好,是构造压应力下的产物,可作为构造应力的标志,它对我国西北新生代勘探程度较低的地区可起判别构造压应力方向的作用。

Some intermountainous basins of the Neozoic age occurred in the western Yunnan Province.Granite and metamorphic rock constituted the basement of the basin with better uranium source conditions.The grey coal-bearing formation was considered as mountain land flurial outwash-dilurial facies and lake-bog facies obviously inherited from the material and composition of the basement′ rock. The interbeding sand and mud were poorly cemented with sound permeability and pressure water,which were favourable for the...

铁南勘探区部分岩石可钻性为8级,研磨性中等,煤层以粉煤为主,胶结性差。针对该区煤心采取率低的情况,对绳索取心金刚石钻头进了了改进:一改钻头形状为三环尖齿底唇形状;二是根据不同地层及岩性选用不同胎体硬度金刚石钻头、不同的金刚石粒度与浓度;三是在底喷钻头水口处加设隔水墙,并改变倒角方向。
