mineral veins

同根派生

The pegmatite Nb-Ta mineral veins were controlled by a group of horizontal tenso-shear axial-direction fault-fissure systems in the NNE direction folding structures.
鈮鉭偉晶巖礦脈受控于NNE向褶皺構(gòu)造的一組近水平張扭性軸向裂隙系。
When the mineral veins are buried deep in the earth, it is necessary to excavate shafts and tunnels to reach the ore body. There are many types of shafts andtunnels in a mine.
如果礦脈在地下埋藏較深，就必須挖掘井巷以通達(dá)礦體。井下井巷的種類有許多種。
There is a vein of melancholy in his character.
他的性格中有少許憂郁的氣質(zhì)。
He doubles the parts of a farmhand and a miner.
在這出戲里他既扮演雇農(nóng)又扮演礦工。
These mineralized vein bodies are usually distributed within fractures of regional fault with medium or low dip angle near surface and high angle bellow or their alternating occarrences.
礦化脈體多分布在區(qū)域斷裂的裂隙構(gòu)造中，礦化體在地表以中（或低）角度產(chǎn)出，向下以高角度產(chǎn)出，或者兩者交替產(chǎn)出形成類似于傾斜的“階梯”狀。
