Permian salt dissolution, alkaline lake basins, and nuclear-waste storage, Southern High Plains, Texas and New Mexico

摘要: Areas of Permian salt dissolution associated with 15 large alkaline lake basins on and adjacent to the Southern High Plains west Texas eastern New Mexico suggest formation by collapse strata over cavities. However, data from 6 other reveal no evidence underlying dissolution. Thus, whether were initiated subsidence areas or was caused infiltration overlying water is conjectural. fact that lacustrine fill in Mound Lake greatly exceeds amount beds indicates at least basin antecedent The association topography, structure, well removed zones shallow burial emphasizes susceptibility salt-bed throughout Texas–eastern area. Such evidence, combined previous studies documenting surrounding a proposed high-level nuclear-waste repository site Deaf Smith County, Texas, leads serious questions about rationale using for storage.
