Stratigraphic evidence for anthropogenically induced coastal environmental change from Oaxaca, Mexico
This paper uses stratigraphic data from sediment cores extracted from Laguna Pastoria, an estuary in the lower Río Verde Valley, to examine changes in coastal geomorphology potentially triggered by highland erosion. Coastal lagoon sediments contain
a stratigraphically and chronologically distinct record of major hurricane strikes during late Holocene times, possibly caused by increased El Niño frequencies. These environmental changes may have had significant effects on human populations in the region.
Stratigraphical and palynological appraisal of the Late Quaternary mangrove deposits of the west coast of India
The organic deposits derived from the mangrove swamps form reliable stratigraphic makers within the Late Quaternary sequence of Kerala-Konkan Basin. Three generations of such deposits have been identified. Pollen analyses confirm that the deposits

excavations of buried tamarisks and willows with stratigraphic mapping to develop a highly detailed and precisely dated stratigraphic cross-section of the floodplain of the Rio Puerco, a rapidly filling arroyo in New Mexico. From 1936 to 1986, sediment
volcanism in this part of the Central Apennines has allowed for the acquisition of some useful morpho-stratigraphic, palaeoenvironmental information. This sector is a key area to be considered for a future morpho-evolutional reconstruction of the entire
This study presents a new interpretation for soil pendant development from the Pahranagat Valley. This process is developed from an extensive micromorphic investigation of the stratigraphic position of laminae and their relationships to the parent
Shoreline geomorphology, shoreline stratigraphic position, and radiocarbon dates of organic material obtained from trench and quarry exposures provide evidence for 2 significant post-Lahontan highstand lake transgressions in the Pyramid Lake
High-resolution seismic stratigraphy has been applied to the interpretation of the stratigraphic architecture of the Late Pleistocene and Holocene successions on the continental shelf and upper slope of the Gulf of Castellammare, North-Western
Contemporary knowledge on aeolian dune dynamics is reviewed to enable an appraisal of evolutionary mechanisms involved in linear dune stratigraphic sequence development. The degrees of depositional record retention in the dune structures

separate phases of accumulation of fine-grained lake deposits, which are correlated with the late High Glacial (Marine Isotope Stage 2), the Middle Würmian (MIS 3) and the pre-Würmian. The Middle Würmian sediments are of particular stratigraphic importance
Stratigraphic and structural relationships among successions outcropping in the area of Nocera and Serra Maggiore (calabro-lucanian boundary) have been investigated and three different successions have been identified (the Nocara Succession
Eruption of central El Salvador's Llopango Volcano, early in the first millennium A.D., left a time-stratigraphic marker in western El Salvador and adjacent Guatemala, the Llopango Tierra Blanca Joven, or TBJ tephra. Analyses of glass from the TBJ
The AA. present a new stratigraphic (pollen and nonpollen microfossils and charcoal particle) sequence with 5 AMS dates, covering about the last 9000 yr, of a core collected from the Spanish northern meseta, in a region known as Tierra de Pinares
-Tethys domain, where sedimentological and stratigraphic data allow to check climate simulation results against geological data. The climatic simulations show that paleoclimates differ between Western Europe and North Africa. In Western Europe
This investigation uses a multidisciplinary approach including geomorphic surface mapping, soil stratigraphic analysis, radiocarbon dating and optically stimulated luminescence (OSL) dating to investigate the chronology of soil formation and aeolian

This study is the first large scale examination of the stratigraphic relationships of acid sulfate soils in Australia. Field and laboratory data from 346 excavated acid sulfate soil profiles for an extensive soil survey undertaken to map
