摘要
构造能在空间形成一个隐伏的环境，而这种环境正是火山尘凝灰岩赋存的重要条件。有了这样一个环境，矿体就大大地降低了所受风化剥蚀的程度。对于火山尘凝灰岩这样一种具有广泛开发前景的非金属矿种，应用构造控矿这一方法去找寻，有可能产生好的效果。
The regional metallogenic geological setting and basic geological characteristics of volcanoc ash tuff deposits have been summarised in detal. Further, the ore - control conditions of structure is analyzed. Comprehensive research has shown that structure can make some conceal environments of formation of volcanic ash tuff in space. It is in this environment that degree of weatheting and denudation of orebody can be reduced largely. As to non - metallic minerals of structure ore - control and the ore - prospecting direction of new volcanic ash tuff deposits.
