Marine archeology in the Gulf of Khambhat - earlier known as Gulf of Cambay - centers on findings made in December 2000 by the National Institute of Ocean Technology (NIOT). These were seen by the scientists involved to be the extension of the present day major rivers of the area.
In a similar marine survey, in a Coastal Research Ship during 1999-2000 when Dr S Badrinaryan was the Chief Scientist, several unusual frames of Side Scan Sonar images were encountered.
Two specimens selected for comparative dating with the electron spin resonance (ESR) method yielded ages of the correct order of magnitude.
Excellent agreement was obtained between U ages after detrital effects were corrected for by reference to modern comparative material for both calcitic and aragonitic specimens, which suggests that uranium-series dating of pre-Holocene molluscs may give reliable results provided the depositional history of the shoreline is well documented.
Make the expat move with a spouse and children in tow, and you’ll slot relatively easily into a life filled with play-dates and school runs, and make friends through both.This is a typical setting in today’s dating scene: you went through college dating a bunch of people and never thought of relationships beyond graduation.Suddenly you hit your mid 20s and you’re either with a job or wasting your time at home and you soon realize that one night stands or passing hookups are not cutting it anymore, because you need someone who can stand by your side, someone you can spend the next couple of years with, someone who you can talk to without trying to pick them up in a bar, basically, finding a partner. Uranium-series disequilibrium methods have yielded the requisite ages for reef coral ranging from 5,000 to 300,000 yr but previously have proved unreliable for most molluscs, the major source of uncertainty being postmortem migration of uranium and its daughter radionuclides into and out of the shells.In the present study the was applied to molluscs from Holocene beaches in the Persian Gulf which had been removed from marine influence by seismic uplift.We present the results of a apatite fission-track (AFT) study on intrusive rocks in the southern Gulf of California, sampled along the eastern margin of Baja California Sur (western rift margin), as well as from islands and submerged rifted blocks within the Gulf of California, and from the conjugate Mexican margin (Nayarit state).For most of the samples U-Pb zircon and Ar mineral ages were already available (Duque-Trujillo et al., 2015).But after college, things get a little more complicated!Here is the call for help; these couple of words would resonate with thousands out there who are facing the same problem: “My friend Andrew and I are both approaching our mid 20s and are single. Neither one of us have received as much attention as we thought we would.Coupled with the new AFT data these ages provide a more complete information on cooling after emplacement.Our samples span a wide range of ages between 5.5 ± 1.1 and 73.7 ± 5.8 Ma, and show a general spatial distribution, with late Miocene AFT ages (about 6 Ma) aligned roughly NW-SE along a narrow offshore belt, parallel to Baja California Peninsula, separating older ages on both sides.
