查询词典 concave

Deep structure in the mantle concave or convex edge of mantle, Moho-discontinuity isobath or local turning control the regional metallogenic belt in distribution; major fault zones and their recombination region control the metallogenic zone; great fault depression, that is, overall depression in the context of uplift, that is, or local uplift in the background of overall fault depression, or the local stronger depression in the background of overall fault depression, all of these special structures are often the enriched areas of ore-forming elements and potential prospects.

深部构造，在幔凹或幔凸的边缘、莫霍面等深线密集或局部突出地段、扭曲端等控制区域成矿带的展布；大断裂带及其复合部位控制矿集区和大型矿床的产出；大断裂断陷构造，即隆中坳，或总体坳陷背景下的局部隆起，即坳中隆，或总体坳陷的背景下的局部更为强烈的坳陷，即坳中坳，所有这些特殊的构造部位，往往也是成矿元素的富集区和成矿远景区。

Self-buckled kerbstones consist of two different layers of compound cement. They are of many kinds of designs and colors. On the outer layer, there are illuminating materials made by special materials. The inner layers are made of common cement, so they are low in price.
