陨硫钙石（CaS）通常被认为是由太阳星云气凝结而成。顽火辉石陨石是陨硫钙石最重要的储存库之一，也是最还原的一类陨石，其是形成早期地球的代表性物质。因此，陨硫钙石对深入了解太阳星云、陨石、地球起源和地球的C-O-S-Ca循环具有重要意义。
在海洋同位素均衡中，地下水输入的溶质通量长久以来被认为是不变的，且经常被忽视，即使不能完全忽视，也将这一部分归于河流输入的通量。由于缺乏对地下水排泄溶质通量的约束，海洋同位素δ7Li、δ26Mg、δ44/42Ca、87Sr/86Sr、δ88/86Sr和δ138Ba的均衡和依赖它们的准确性建立的地球系统模型存在巨大不确定性。

Understanding catfish ecology is important because catfish constitute one of the largest fish stocks in the coastal IndoPacific
regions. Recent technological advances have enabled the use of biologic...
