Aspects of the Hydrology and Hydrogeology of the Northern Yucatan Peninsula, Mexico

这是一项旨在描述墨西哥尤卡坦半岛北部的水文、水文地质和地球化学特征的建议。尤卡坦北部是一个发育岩溶特征的新兴地台，岩石矿物学以石灰岩和白云岩为主。低泥质矿物含量和高渗透率确保了系统中地下水的快速吞吐。淡水和咸水的混合导致淡水透镜体和下伏的咸水侵入体之间有一个显着的弥散区；这个弥散区会显著影响碳酸盐的成岩作用。简单的地层和矿物组成、可访问性以及缺乏人类开发使尤卡坦半岛北部成为一个极好的天然实验室。研究区将划分为渗透率差异较大的四个不同区带。拟议的研究包括钻孔(与墨西哥离子含量、环境同位素、饱和指数和锶含量合作)，以及进行和校准电阻率测量。将研究界面行为及其与成岩作用和腐蚀的关系。数据将被绘制成地图或等高线，并用于地下水流动的数值模拟。

This is a proposal to characterize the hydrology, hydrogeology, and geochemistry of the northern Yucatan Peninsula, Mexico. Northern Yucatan is an emergent platform in which karst features are developing in rocks whose mineralogy is strongly dominated by limestone and dolomite. Low content of argillaceous minerals and high permeability insure a rapid throughput of groundwater in the system. Mixing of fresh and salt water result in a significant zone of dispersion between the fresh groundwater lens and the underlying saline intrusion; and this zone of dispersion can significantly affect carbonate diagenesis. Simple stratigraphy and mineralogical composition, accessibility, and lack of human development make the northern Yucatan Peninsula an excellent natural laboratory. The study area will be divided into four distinct zones characterized by strong differences in permeability. Proposed research involves drilling holes (in collaboration with Mexican ion content, environmental isotopes, saturation indices, and Sr content), and making and calibrating electrical resistivity surveys. Interface behavior and its relation to diagenesis and corrosion will be studied. Data will be mapped or contoured and used in numerical simulation of groundwater flow.
