fissure vein

In exposed rock areas and worked out mines, structure rock fissure survey and vein rock survey can be employed to trace deep blind orebodies.

在岩石裸露区和已开采的矿山采用构造岩石裂隙测量和脉岩测量追踪深部盲矿；

In addition, we also found one case of rare variants of the lateral fissure vein, 1 ( 1%). 2.

除此之外，我们还发现1种罕见变异类型的外侧裂静脉，占1%。

Observe the shape, number, distribution and classification of the lateral fissure vein in the operations, and measure the related data.

术中观察外侧裂静脉的形态、数目、分布及分型，并测量相关数据。

The skarn wolfram deposits are formed in granite contact zone and crack of stratum. The porphyry and quartz vein molybdenum deposits are formed in porphyritic granite bodies and fissure vein.

小柳沟矿区有着三（多）位一体的成矿系列，岩体外接触带和地层层间裂隙形成以夕卡岩型为主的白钨矿，岩体内部及岩体顶部形成斑岩型和石英脉型钼矿。
