白垩纪Okorusu碳酸岩，纳米比亚，包括透辉石轴承和伟晶方解石碳酸岩，都表现出热液蚀变矿物组合。在未蚀变的碳酸岩中，Sr、Ba和稀土元素（REE）主要赋存于方解石和氟磷灰石中。然而，在热液蚀变碳酸岩中，小（
The Cretaceous Okorusu carbonatite, Namibia, includes diopside-bearing and pegmatitic calcite carbonatites, both exhibiting hydrother-mally altered mineral assemblages. In unaltered carbonatite, Sr, Ba and rare earth elements (REE) are hosted principally by calcite and fluorapatite. However, in hydrothermally altered carbonatites, small (
