Based on the observation and statistics on the calcareous sandstone in the ore host layer in shihongtan uranium deposit, this paper finds that the calcareous sandstone occurs on and off near the top or wash surface of the sandbody as beads - strings lens along the layer and concentres in the area where the orebodies are rich
摘要通過對十紅灘鈾礦床容礦層鈣質砂巖的觀察和統計，發現鈣質砂巖呈順層、斷續的串珠狀透鏡體分佈，產出空間位置為砂體的頂底部或沖刷面，而且較集中的分佈在礦體發育區。 -
According to the analysis on the lithogeochemical features and the carbon and oxygen isotopes of calcareous sandstones, it is realized that there some genetic relation between the formation of calcareous sandstone and uranium mineralization in the oxidation - deoxidation transitional belt, that is the precipitation and enrichment of uranium is accompanied by the deposition of carbonate and formation of calcareous sandstone
根據鈣質砂巖的巖石地球化學特徵，結合碳、氧同位素分析認為，氧化還原過渡帶中鈣質砂巖的發育與鈾礦化的形成具有一定的成因聯系，即在鈾沉澱富集成礦的同時，伴隨著碳酸鹽的析出作用，形成鈣質砂巖。 -
