Neritic Sedimentary Facies

2010
Understanding this vast depositional realm has been a protracted study. As each new sector of the continental margin was documented, the new findings necessitated re-evaluation of previous interpretations. This chapter is the result of a total re-study of all bottom samples acquired since 1989 and their placement in a facies scheme that is applicable ...

Sedimentary facies of iron formation

Economic Geology, 1954
Discussion of conclusions relative to the intensity and duration of chemical weathering during the Precambrian contained in a paper on the origin of the iron formations of the Lake Superior district; points out that lateritic iron ores locally more than 100 meters thick are being formed at present by chemical weathering processes in the Conakry ...

Sedimentary facies as indicators of Mesozoic palaeoclimate

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993
Abstract Sedimentary facies alone provide equivocal, and qualitative, evidence about Mesozoic climates and climate changes. The most climatically informative sediments are laterites, evaporites and aeolianites. Tills would also be unequivocal where present. A range of other criteria (e.g.

Sedimentary Facies in Gulf Coast

AAPG Bulletin, 1949
ABSTRACTS The Gulf Coast of Texas and Louisiana belongs to a world community of Tertiary provinces that have been extensively drilled for oil, and in which the sedimentary characteristics of the producing formations are similar to the characteristics of modern sediments in the same regions to-day.

Tide-influenced sedimentary environments and facies

Marine Geology, 1988
This volume contains examples of recent as well as fossil tide-influenced sedimentary facies. Studies of recent tidal processes and sediments provide an insight into the way in which tidal facies and sequences develop, and into the processes which are active.
