對于鉻鐵礦礦層產狀的了解同樣是不完整的。The intense eluviation and weathering of soil with groundwater and run - off result in the enhancing of capacity of transference of some elements, such as si, al, fe, mn. the chemical reactions of the colloid particles in the soil water make those crannies or holes filled by some epigenetic clay minerals and quartz. then a great deal of white reticulate clay comes into being in the quaternary laterite of the dongting basin
地下水和地表水強烈的淋溶作用使土壤中硅鋁鐵錳等元素的遷移能力增強，土壤膠體粒子之間的化學反應，使得這些孔隙空間在後期逐漸被次生黏土礦物和石英所充填，最終，在洞庭盆地第四系紅土地層中形成大量的蠕蟲狀和根狀白色網紋。Layered mafic intrusions not only represent natural laboratories for studying processes of magmatic differentiation and assimilation within the crust, but also contain extensive precious and base metal mineralization
層狀鎂鐵質巖體不僅是研究巖漿分異演化過程和地殼混染作用的最佳天然實驗室，其中還廣泛賦存重要的稀有金屬和賤金屬礦床。Surface settlement is due to layer losses and the layer losses are due to the changes of stress state and water content. it is necessary to probe into the principle, but to pay more attention to the aftermath of layer losses - surface settlement and its regularity. this paper has focused on discussing about the regularity of surface settlement in tunneling construction
地表之所以發生沉降，是因為發生了地層損失，而地層損失主要是由於土的應力狀態和土的含水量發生了變化，機理的探討是必要的，但是人們更關心地層損失造成的後果?地表沉降，更關心地表沉降的規律性，本文討論了隧道施工過程中地表沉降的規律，將隧道施工方法分為盾構法和礦山法兩種，結合理論分析和實測結果，分別給出了地表沉降曲線和沉降范圍的經驗公式，其結論對北京地鐵隧道的設計與施工具有重要的參考價值。Pyritic bedded deposit
