Low temperature aqueous alteration of basalt: Mineral assemblages of Deccan basalts and implications for Mars
[1] Al-rich phyllosilicates (kaolinite, montmorillonite) have been found in layers overlying Fe/Mg-smectites on Mars, and it has been suggested that this stratigraphy formed through in situ leaching at the surface, similar to terrestrial weathering profiles. We are investigating the remotely sensed signatures of this type of weathering using ten samples from a vertical section of altered Deccan...
متن کاملWhat Is the "Hill Fever of Mysore and Deccan"?
Sir,?Can any of your readers give any information as to the nature of what has been called the " Hill Fever" of Mysore and the Deccan 1 In reading an account of malaria* recently, I came across the following: " The hill fever of Mysore occurs among bare rocks, stones and brown earth, at the hottest season from March to June, when the rocks in the sun show a surface temperature of 220?F. and rap...
متن کاملBiodiversity during the Deccan volcanic eruptive episode
This paper gives a detailed overview of biotic assemblages recovered from the Deccan trap intercalated sedimentary sequences (infraand intertrappean beds) of peninsular India as a result of extensive research done during the last 20 years. The infraand intertrappean beds contain remnants of Gondwanan forms such as myobatrachinae frogs, pelomedusid turtles, dinosaurs (i.e. titanosaurids and abel...
متن کاملRheumatic Heart Disease in the Bombay Deccan
By L. B. CARRUTHERS, b.a., m.d., c.m. American Presbyterian Hospital, Miraj, S. M. C. ' he conception that rheumatic fever and its concomitants are rare or entirely unknown within the true tropics has long been in favour. Seemingly it received strong confirmation when Clarke (*1930) published his notable paper on the geographical distribution of rheumatic fever. Rogers and Megaw (1930) in India...
متن کاملA combined Y/Ho, high field strength element (HFSE) and Nd isotope perspective on basalt weathering, Deccan Traps, India
a r t i c l e i n f o chemostratigraphy of two contrasting Deccan Traps weathering profiles – an ancient, deeply weathered laterite, and a younger (Quaternary), more moderately weathered saprolite – are used to reconstruct different aspects of basalt weathering. Precision of the HFSE analyses is demonstrated through a report of the long-term concentrations and ratios determined in United States...
