  • glaciation
  • The newly mapped basin contains an expanded and largely complete record for paleoclimatological studies of the onset and history of glaciation in the Northern Hemisphere and will further contribute to an enhanced understanding of geohazards and resources constituted by shallow gas reservoirs. (lyellcollection.org)
  • ridges
  • Further analysis of the survey data should help clarify whether the location of the seabed ridges is linked to past seepage from the basin. (ga.gov.au)
  • faults
  • The principal aim of Geoscience Australia's marine survey was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether the location of these features are related to basin structures, such as faults that have been identified in a number of seismic lines, that may extend up to the seabed. (ga.gov.au)
  • These include: in Area 1, northwest trending linear structures, suggestive of faults, present on the seabed. (ga.gov.au)
  • adjacent
  • This occurs through a variety of processes including precipitation, firnification, and wind transportation of snow into a glacier basin from an adjacent area. (usgs.gov)
  • continuous
  • A continuous accumulation of snow and glacier ice that completely fills a mountain basin or covers a low-relief mountain plateau to a substantial depth. (usgs.gov)
  • minerals
  • Halite is constrained to local depressions in the ancient southern highlands, suggesting precipitation from the evaporation of water in closed basins at ~3.5-4 Ga. The presence of oxychlorine minerals on the martian surface has important implications for the habitability of present day Mars because oxychlorine minerals may deliquesce to create seasonal deposits of liquid water.

  • several
  • Several key seabed features were identified using the new geophysical data, and are being investigated in order to understand the relationship between the present seabed and the geological history of this shelf, and to provide an understanding of possible fluid seepage from the underlying Vlaming Sub-basin. (ga.gov.au)
  • Area
  • It occupies an area about 585 square miles in size containing five major creeks (Schohaire Creek, Esopus Creek, Stony Creek, Batavia Kill, and Rondout Creek) and two reservoir basins: Schoharie and Ashokan. (fws.gov)
