The origin of the stratiform tin deposits in the schist belt of the Stara Kamienica Chain, southwestern Poland, is re-examined based upon new data which has become available. It is the author's opinion that no genetic implications should be attached to the stratiform character of the deposits. Hydrothermal metasomatism associated with acid intrusives of the Variscan Karkonosze massif introduced mineralizing fluids along tectonic lineaments. 相似文献
