Discontinuous outcrops or marine rocks provide clues of former trans-peninsular seaways. Topographically, only a few low-elevation locations along the drainage divide permit a trans-peninsular seaway (e.g. Biologists frequently call upon trans-peninsular seaways to explain these patterns. Mitochondrial DNA and allozyme data suggest these breaks occurred ~1-2 Ma. The group discussed the evidence from numerous terrestrial species showing a genetic break between northern and southern populations in the center of the peninsula. These seaways would have created physical boundaries for many terrestrial species, and allowed dispersal between the Pacific and Gulf for marine taxa until seaway closure. The discussion focused largely on trans-peninsular seaways that are hypothesized to have existed across the Baja California peninsula at the latitudes of San Ignacio/Santa Rosalia (~9-12 Ma and ~1.5 Ma) and La Paz (pre-3 Ma). The group discussed the evidence for marine seaways in the Gulf of California and the role these may have played in the diversity, distribution, and speciation of marine and terrestrial organisms. El Mayor-Cucupah, Ballenas channel) are evidence of active faulting along PAC-NAM plate boundary – consists of multiple, discontinuous, right-lateral, strike-slip faults that connect extensional basins (pull-apart basins) that are bound by normal faults – present-day PAC-NAM plate boundary is located along the center and western portion of the Gulf of California and is directly connected to the San Andreas fault system in southern California – large marine basins open up and are formed during this period throughout the Gulf – PAC-NAM plate boundary during modern-Gulf period (6 -0 Ma) was characterized by more localized faulting – plate boundary between the Pacific and North American (PAC-NAM) tectonic plates during the proto-Gulf period (12.5 – 6 Ma) was characterized distributed across a wider region, known as the Gulf Extensional Province – at 12.5 Ma, the plate boundary along Baja CA evolves from subduction (compression) to transtension (both extension and right-lateral relative motion) – subduction zone offshore western Mexico – chain of volcanoes (Comundu arc) along axis of future Gulf of California – widespread volcanic eruptions and deposition of andesite lava flows and volcanic-rich sedimentary rocks along the peninsula’s eastern margin The session began with an introduction to the geologic evolution of the last 25 million years of the Gulf of California region, shown via paleogeographic maps and an animated tectonic reconstruction. In this session, discussion will focus on the current state of binational research pertaining to the 4-D geologic evolution of the Gulf of California (in both time (1- D) and space (3-D)) and how this evolution has created the modern geological setting of the Gulf of California.
