一辆BSTRACT。-在过去二十年中，关于瓜达-卢佩山脉从晚二叠世到现在的地质史，提出了一些新的观点。本文将讨论其中的六个想法。P.B.King的经典模型认为霍维海峡是二叠纪盆地的入海口，但新的证据表明，入海口位于特拉华州盆地的盐盆一侧，而不是格拉斯山脉一侧。瓜达卢佩山脉的“第一阶段fiSure喀斯特”现已被确定为形成于瓜达卢佩(晚二叠世)时期的岩溶-莫迪-fi同沉积断裂。“二期海绵岩溶”代表了中生代(侏罗纪)石灰岩中生过程中卡普坦含水层水的缓慢扩散循环。瓜达卢佩山脉的硅质顶端砾石很可能是科曼奇(早白垩世)时代的考克斯砾石。瓜达卢佩山脉的“第二阶段尖晶石洞穴”可追溯到拉拉米德早期(白垩纪晚期)，代表了一个深度循环的热液时代。大型“第四阶段洞穴通道”(如卡尔斯巴德、列楚-圭拉)主要由硫酸而不是碳酸形成。从特拉华盆地的烃类反应中产生的硫酸，该反应产生了fide
A BSTRACT . —A number of new ideas have been proposed over the last two decades regarding the geologic history of the Guada-lupe Mountains from the Late Permian to the present. This paper will discuss six of these ideas. The classic model of P. B. King has the Hovey channel as being the inlet for the Permian basin, but new evidence suggests that the inlet was on the Salt Basin side of the Delaware basin rather than on the Glass Mountains side. The “Stage 1 fissure karst” in the Guadalupe Mountains has now been established as karst-modified syndepositional faults formed in Guadalupian (Late Permian) time. The “Stage 2 spongework karst” represents the slow diffuse circulation of Capitan aquifer water during limestone mesogenesis in the Mesozoic (Jurassic). The siliceous summit gravels of the Guadalupe Mountains are most likely Cox gravels of Comanchian (Early Cretaceous) age. The “Stage 2 spar-lined caves” in the Guadalupe Mountains date from the early Laramide (Late Cretaceous) and represent a time of deeply circulating, hydrothermal solutions. The large “Stage 4 cave passages” (e.g., Carlsbad, Lechu-guilla) formed primarily from sulfuric acid rather than carbonic acid. The sulfuric acid derived from hydrocarbon reactions in the Delaware basin that generated hydrogen sulfide
