Colombia is a country rich in coal deposits; however, there are few published studies characterizing these coals in detail from a scientific perspective. This study investigates the thermal maturity and depositional environment of a coal seam from the Guaduas formation (Maastrichtian-Paleocene) of the Eastern Colombian Cordillera Basin, providing insight into burial and temperature history and changes in the depositional environment over time. This three-meter-thick hard coal seam reflects about 20 m of former peat deposition, representing a period of roughly 10.000 years.

有机岩石学和地球化学数据揭示了哥伦比亚东部科迪勒拉山脉瓜杜阿斯组煤的沉积和热历史


哥伦比亚是一个煤炭储量丰富的国家；然而，很少有已发表的研究从科学角度详细描述这些煤炭的特征。本研究调查了哥伦比亚东部科迪勒拉盆地瓜杜亚斯组（马斯特里赫特-古新世）煤层的热成熟度和沉积环境，深入了解埋藏和温度历史以及沉积环境随时间的变化。这个三米厚的硬煤层反映了约 20 m 的前泥炭沉积，代表了大约 10,000 年的时期。
