Wood tin and colloform cassiterite belong to the series of cassiterites,but water tin is still unknown to the people. 木錫石、膠狀錫石均為錫石的一種，水錫石則是研究得不很清楚的一種礦物。

In some high-grade disseminated ores, sulfides are also encountered as bands, reniform masses, and coatings associated with colloform textures. 有些高品級浸染狀礦石中,硫化物類也成層帶、腎狀塊,與膠體結(jié)構(gòu)共生。

Ore minerals, colloform and microcrystalline apatites, are identified as francolite through X-ray diffraction analysis, with a fine . 礦石礦物為膠狀磷灰石和微晶磷灰石,經(jīng)x-射線衍射物相分析,其種屬為含碳氟磷灰石。

Colloform, frambo idal textures and laminated, brecciated structures of exhalation are widely deve loped in the stratiform ores. 礦石發(fā)育膠狀和莓球結(jié)構(gòu)，微細(xì)層紋狀_ 馬尾絲構(gòu)造。
