The late ordovician - silurian - devonian - early carboniferous stratigraphic division and correlation , including the chronologic correlation of the donghe sandstone , which are the old great difficult key stratigraphic problems interfering with the development of the oil and gas exploration in the tarim basin , are synthetic studied by systematically applying chemobiostratigraphy . several important relevant stratigraphic boundaries are recognized , and the donghe sandstone is attributed to the frasnian , late devonian . the results of the study in particular proves that chemo - biostratigraphy has great significance and is a practical tool for high resolution stratigraphic division and correlation , especially for the region and or the bed with rare fossils 首次系統應用化學生物地層學對長期遺留的嚴重阻礙了油氣勘探開發步伐的塔里木盆地重大疑難地層問題：晚奧陶世志留紀泥盆紀早石炭世地層劃分對比和東河砂巖時代等進行了綜合研究，厘定了幾條重要的相關地層界線，并將東河砂巖的時代確定為泥盆紀晚泥盆世弗拉斯期。這些研究成果表明，化學生物地層學對高分辨率地層劃分對比尤其是對在化石缺乏地區和層段進行地層劃分對比工作有重要的意義和實用價值。

The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment . during the past two decade , the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants , provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants . three new plant based epochs have been recognized . on the other hand , molecular sequence studies have provided insights into the phylogeny and early branches of land plants . a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences . this paper summarizes recent advances and new knowledges , comments on the phylogenetic studies based on the cladistic analysis 陸生植物的起源和演化是地球生命中的重大事件，它影響到地球上所有的其他生命和全球環境。在過去的20年中，從中奧陶世歷經整個志留紀至早泥盆世的巖層中，化石植物微化石和大化石的新發現改變了人們對陸生植物起源的認識，并且為陸生植物和維管植物早期演化分異提供了基部類群分化的時間框架。據此人們識別出地史中的3個陸生植物的時代：始胚植物時代始維管植物時代和真維管植物時代。

In the concentrated mineralization area , there are many types of pb - zn - ( ag ) deposits and gold deposits , it is one of bases of lead - zinc in china . in this area seafloor hydrothermal sedimentary ore deposits and hydrothermal sedimentary - rebuilded ore deposits are predominated . all lead - zinc - ( silver ) and gold deposits hosted in devonian sedimentary rocks , and orebodies of seafloor hydrothermal sedimentary deposits and hydrothermal sedimentary - rebuilded deposits draped in phase with stratum 礦化集中區內主要的礦床類型是熱水沉積型和熱水沉積改造型，其中熱水沉積成礦作用形成的廠壩-李家溝礦床為超大型礦床，熱水沉積-改造型礦床有畢家山和鄧家山等大型鉛鋅(銀)礦床，礦床與中泥盆統地層整合產出，并同步褶曲。
