无机矿物质按照砂岩和泥岩的顺序沉积着，并随着周围的自然环境演变为海洋性，由石灰石覆盖在了最上层。
Organic materials were deposited in sequences of sandstone and mudstone, which were then covered by limestones as the environment became progressively more Marine.
这种物质硬如磐石（石灰石主要就是由碳酸钙构成的），但易溶于酸。
The stuff is tough as a rock (limestone is made primarily of calcium carbonate), but it dissolves instantly in acid.
她说道：“这想技术基于水和油的化学性质，它们的特殊性质能将二氧化碳转化成石灰石类物质。”
She said: "This technology is based on the chemistry of oil and water and has the special property of transforming carbon dioxide into a limestone-like substance."
