【摘要】 九毛锡矿床存在一个高－中－低温成矿作用序列，锡矿床主要形成于中－低温（２６０—１６０℃）阶段。矿床具有明显的低温变形特征，主要表现为锡石、石英等矿物颗粒的晶体塑性变形、重结晶（动态和静态）、变形纹、波状消光、吕德尔线、构造脉，劈理和构造透镜体，反映出低温变形作用对成矿物质具有重要的改造富集作用。研究表明，作为低温变形的一种重要变形机制—压溶作用，也是九毛锡矿低温成矿的重要机制。更多还原

【Abstract】 There is a high,middle and low-temperature metallogenic series at Jiumao. tin deposit,with the main oreforming stage ranging from. 26O℃ to 160℃. The deposit has some low-temperature characteristics, suech as grain-scale crystal plasticity of cassiterite 5 quartz etc.dynamically and statically recrystallized grains, deformation bands,undulatory extinction,. luders’bands, tectonic veins, cleavages and tectonic lenses. The pressur-solution is a kind of important lowtemperature deformation mechanism and may be a kind of important low-temperature ore-forming Process mechanism at Jiumao tin deposit.更多还原
