摘要

MILY: ’Times New Roman’; FONT-SIZE: 14pt; mso-fareast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>The southern ml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />me w:st="on">Jiangxime> Province is known as “the world tungsten city”, and the Longnan-Dingnan-Quannan (“Sannan area” for short the same below) is an important tungsten-bismuth metallogenic region in this area. Tungsten-bismuth mineralization is closely related to the Devonian strata distributed widely in the Sannan area. Based on the preliminary study and discussion on the distribution and abundance of trace elements of the Devonian strata as well as abundance of W-Bi ore-forming elements in different lithologic rocks from the Sannan area, the authors consider that the abundance of W ore-forming elements of the Devonian strata is only next to that of Cambrian strata, but it is higher than that of the other strata of various ages and is 2-4 times higher than that of the Clarke value. Among the different lithologic rocks, the fine-grained clastic rocks have the maximum W-Bi contents and the most closely genetic relation with W-Bi mineralization.
