| A Sedimentological Study of Carboniferous Bauxitic Formations in North China |
| |
| 摘 要： | The authors have found in their studies many new genetic types of microtextures of bauxite. A sedimentological genetic classification of bauxites based on these features and a division of the microfacies types of bauxites formed in major microenvironments are proposed. Four kinds of sedimentary sequence of bauxitic sediments have also been recognized. On these bases, a generalized sedimentary model of Carboniferous bauxites in North China is presented, in which storm-turbidite currents play an important role in the formation and enrichment of bauxite deposits.
