The magnetostratigraphy, fission-track dating, and stratigraphie evolution of the Peshawar intermontane basin, northern Pakistan
The Peshawar basin is situated along the junction of the northern margin of the IndoGangetic foredeep and the southern margin of the Hindu Rush-Himalayan Ranges. During the late Cenozoic, southward encroachment of tectonic disruption into the foredeep terminated molasse deposition and delineated the Peshawar intermontane basin through uplift of the Attock Range along the southern margin of the ...
متن کاملAnalysis of 14C and 13C in teeth provides precise birth dating and clues to geographical origin.
The identification of human bodies in situations when there are no clues as to the person's identity from circumstantial data, poses a difficult problem to the investigators. The determination of age and sex of the body can be crucial in order to limit the search to individuals that are a possible match. We analyzed the proportion of bomb pulse derived carbon-14 ((14)C) incorporated in the enam...
متن کاملAMS 14C dating of Holocene estuarine deposits: consequences of high energy and reworked foraminifera
Benthic foraminiferal species were used to AMS date Holocene sediments adjacent to transgressive overlap boundaries (TOB) in two high energy estuaries in North Spain. It had previously been recognised that the foraminifera could be divided into indigenous and exotic components. Whereas it was known that the exotic forms had been transported into the estuaries from the adjacent inner shelf, it w...
متن کاملCorrelating the Ancient Maya and Modern European Calendars with High-Precision AMS 14C Dating
The reasons for the development and collapse of Maya civilization remain controversial and historical events carved on stone monuments throughout this region provide a remarkable source of data about the rise and fall of these complex polities. Use of these records depends on correlating the Maya and European calendars so that they can be compared with climate and environmental datasets. Correl...
متن کاملC:N:P Molar Ratios, Sources and 14C Dating of Surficial Sediments from the NW Slope of Cuba
The surficial sediments recovered from 12 sites located near the channel axis of the Florida Straits and the lower slope off NW Cuba were analyzed for total organic carbon (TOC), nitrogen (TN), phosphorus (TP), elemental C:N:P ratios, C and N isotopic values, and 14C dating. The depth profiles of TOC, TN, and TP (0-18 cm) displayed a downcore trend and a significant variation. The TOC values we...
