Detailed geologic mapping, measured sections, lithofacies analysis, and preliminary paleomagnetic data indicate that sedimentation and deformation in the Mecca Hills resulted from evolution of local fault zone complexities superimposed on regional subsidence and uplift. Sediment was derived from sources northeast of the SAF and transported southeast along the fault zone in large rivers, alluvial fans, and a smaller fault-bounded lake. -

Sedimentation and Deformation in a Pliocene–Pleistocene Transtensional Supradetachment Basin, Laguna Salada, North-West Mexico R
Basin Research (1999) 11, 205–221 Sedimentation and deformation in a Pliocene–Pleistocene transtensional supradetachment basin, Laguna Salada, north-west Mexico R. Dorsey* and A. Martı´n-Barajas† Department of Geological Sciences, 1272 University of Oregon, Eugene, OR 97403–1272, USA †Departamento de Geologı´a, Centro de Investigacio´ n Cientı´fica y de Educacio´ n Superior de Ensenada, Baja California, Mexico ABSTRACT This study examines a thick section of Pliocene–Pleistocene sedimentary rocks exposed in the footwall of an active normal fault (Can˜on Rojo fault) near its intersection with the dextral- normal Laguna Salada fault in north-western Mexico. These rocks are situated in the upper plate of an inactive strand of the Can˜ada David detachment fault, which is cut on the north- east by the Laguna Salada fault. The stratigraphy is divided into three unconformity-bounded sequences: (1) marine mudstone of the Pliocene Imperial Formation; (2) nonmarine Pliocene– Pleistocene redbeds, consisting of sedimentary breccia, conglomerate, conglomeratic sandstone (all un-named) and fine-grained sandstone and mudstone of the Palm Spring Formation; and (3) uncemented Pleistocene boulder gravel. Coarse deposits of the redbeds sequence were deposited in fault-bounded, high- and low-gradient alluvial fans that passed laterally into a low-energy fluvial plain of the ancestral Colorado River (Palm Spring Formation) which occupied the present-day Laguna Salada. Detailed mapping reveals convergence and lap-out of bedding surfaces in the redbeds sequence onto the west limb of a large anticline cored by Imperial Formation. These geometries, combined with fanning dips and thickening of stratigraphy into the flanking syncline, indicate that the anticline grew during deposition of the redbeds. -

C. ----- Price 20 cents PREFACE By T. W. STANTON In Bulletin 769, " The geologic time classification of the United States Geological Survey," by M. Grace Wilmarth, secretary of the committee on geologic names, it was announced that Miss. Wilmarth had in preparation a more extended compilation which will form a stratigraphic lexicon of the United States, containing definitions of all the geologic formations that have been named and described in this country. Work on this compilation is making good progress and has now reached a stage where it is possible to give geologists a sample of the lexicon, which will be locally useful and at the same time give them an opportunity to make helpful criticisms both of the character of the material to be included in the larger work and of the form in which it is presented. It happens that California is almost completely isolated from the other States in its stratigraphic development and that the great local variations in sedimentation within its borders, epecially in Tertiary time, have caused the naming of an unusual number of formations. Less than half a dozen of the formations named in California extend into Oregon and Washington, and the number that come into eastern California from Nevada is not much larger. It is therefore thought desirable to issue the " Names and definitions of the geologic units of California " as a separate publication. -
