洞穴在地球上无处不在，从热带到高纬度地区，从海平面以下到高山地区。洞穴形态为其形成机制提供了线索，其标志性的矿物学特征——石笋和钟乳石——在其地球化学和矿物学中编码了丰富的古环境信息。最近的工作表明，我们解码这些古环境代用物的能力有了惊人的提高，而地质年代学的巨大进步使得更高分辨率的记录能够进一步追溯到地质时代。洞穴研究解决了越来越多的地球科学问题，从确定气候变化的时间和机制到揭示地磁场行为的详细记录。
Caves occur everywhere on our planet, from the tropics to the high latitudes and from below sea level to alpine settings. Cave morphologies provide clues to their formation mechanisms, and their iconic mineralogical features—stalagmites and stalactites—carry a wealth of paleoenvironmental information encoded in their geochemistry and mineralogy. Recent work demonstrates a striking improvement in our ability to decode these paleoenvironmental proxies, and dramatic geochronological advances enable higher resolution records that extend further back in geologic time. Cave research addresses an ever-increasing range of geoscience problems, from establishing the timing and mechanisms of climate change to uncovering detailed records of geomagnetic field behavior.
