Treat this aspect as serious, and do all you can to not rock the boat with anyone you feel seems a little fragile or ultra-sensitive this month.

人际方面你要认真对待，这个月内尽你所能不要触动那些你觉得非常脆弱和异常敏感的人。

Based on the derivation of metallogenic matters, mineralization and wallrock conditions, the gold deposits are subdivided into three main types: volcanic thermal type, subvolcanic rock-shallow to ultra-shallow porphyry thermal type, and concealed explosive breccia type of gold deposits.

根据其金矿成矿物质来源、成矿作用及产出的围岩条件可划分为火山热液型、次火山-浅成斑岩热液型和隐爆角砾岩型金矿床。

The features of overburden strata movement are thick strata, multi-stages, slow development, synchronously collapse of multi-rock, leading a big abscission layer space, which is easy to connect to pre-existing fracture, forming ultra-high guide water flowing fractured zone.

覆岩运动为厚岩层，多阶段、慢发展，多岩层的同步垮落，导致离层空间大，容易沟通原生裂隙，形成超高导水裂隙带。
