中文拼音 [suìxièyìcháng]
碎屑異常
英文
clastic anomaly-
Beneath the relic sand of the outer shelf there is high grade of valuable heavy mineral sand ( for example ilmenite ) reaching the ii anomaly order of marine placers and it is of potential resource prospects
通過碎屑礦物判斷，原巖應是中酸性巖漿巖和淺變質巖類。鈦鐵礦等有用礦物在細砂層位中出現較厚的砂礦異常，顯示一定的淺海砂礦資源潛力。The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid, meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud, the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks
同時，受熱流體活動的影響，熱流體對火山碎屑巖具有一定改造作用，如在安山質巖屑凝灰巖中，斜長石絹雲母化、火山巖巖屑綠泥石化明顯；在凝灰質泥巖中，熱流體對圍巖中有機碳具有明顯的「催熟」加熱作用，微量元素則出現異常現象。This paper sums up characteristics of au anomalies within tertiary red elastic beds in a certain area of qinghai province, and points out that au anomalies mainly exist in the middle part of the tertiary strata, that anomalies are most strong in stream sediments, and that au anomalies result from secondary enrichment of au
摘要對青海某地第三系紅色碎屑巖層中的金異常特徵進行了綜述，指出金異常主要存在於第三系中段巖層中，異常在水系沈積物中強度最大，並認為金異常由次生富集作用形成。Abstract : this paper sums up characteristics of au anomalies within tertiary red clastic beds in a certain area of qinghai province, and points out that au anomalies mainly exist in the middle part of the tertiary strata, that anomalies are most strong in stream sediments, and that au anomalies result from secondary enrichment of au
