On deposits controlled by tectonic lenses

By study of the typical tectonic lenses controlling some ore deposits, the tectonic lens boundaries may be classified into fuzzy boundaries, sharp boundaries and complex boundaries, and the metallostructures in tectonic lenses may be classified into vein-type, stockwork-type and breccia-type. After studying their metallostructures, we suggest the conception on tectonic lenses as an ore-forming system, realizing that the compact-function ore-forming system is made up of the lenticular weak-strain domain(Q) and its outside linear strong-strain belt(P). The ore-forming system, which is composed of four subsystems that coupled with each other and exert their system functions to the full, includes the dual-dynamical system made up of tectonic and fluid dynamics, the metallotectonic system controlled by hydrofracturing, the ore-source system made up of multi-substances and the mineral transportation system contacted by tectonic network. Deformational partitioning, hydrofracturing and tectonic pumping operate the considerable function while the system function practises. Finally,the significance of metallotectonics on the tectonic lenses is discussed in the paper.
