Abstract

Several ordered cycles of volcanism and sedimentation have been recorded from the Mahakoshal greenstone belt in the eastern part of the Sidhi district, Madhya Pradesh. Each cycle is characterised by pillow lava-pahoehoe toes, bomb agglomerate. volcanic breccia and tuff, culminating with the deposition of massive chert under quiescent conditions. The volcanics and the sediments exhibit linear distribution and were deposited as a result of eruptions along ENE-WSW trending fissures, parallel to the margins of the belt. The deposition of volcanics and sediments took place over thin Archaean sialic crust where tholeiitic magma differentiated at a depth of less than 15 km.

Abstract

The lowermost formation of the Bagh Group, the Nimar Sandstone, was deposited in fresh water whereas the upper two formations, the Nodular and Coralline Limestones were deposited in marine environment There is a distinct signature of diagenetic alteration in the oxygen isotopic ratios but the carbon isotopic ratios did not change signi ficantly. The marine transgression from the continental Nimar period to upper Limestone period was extremely rapid in all four sections (Mogra, Rampura, Acharkunda and Bariya) examined. However, the subsequent regression during the onset of the Lameta period was slow and fluctuating. The oxygen isotope ratios of some limestones from the Kawant area (Mogra section, Nodular Limestone Formation) are unusually low probably due to thermal alteration effected by intrusion of the nearby Ambadongar Carbonatite at a later date.

Abstract

The Cretaceous sedimentary basins of lower Narmada valley covered a vast region in the western India and presently a large part of these basins are under the Deccan Trap cover. The geology of the exposed part shows development of continental facies with an intervening marine transgressive facies. The Nimar- Bagh- Lameta sequence was studied for their regional tectonic framework, stratigraphy and basin evolution. It has been observed that the marine transgression was limited to the Half-Grabens paralleling the Precambrian tectonic fabric. The Bagh area (Madhya Pradesh) is contemplated to represent a Cretaceous triple point junction formed due to the reactivation of Precambrian tectonic gram during the anticlockwise movement of India plate. A detailed stratigraphy of the area has been proposed. The continental Nimar Sandstone Formation was deposited in a large westerly sloping topographic basin. The marine transgression at the end of the Nimar period resulted into the deposition of Bagh Group. The overlying continental Lameta Group shows varied sedimentation in space and time. The calcareous sandstone and limestone with chert concretions containing dinosaur skeletal remains are the most widely deposited facies of the Lameta Group and have a striking similarity with that of the Lower Limestone (Lameta Group) of the upper Narmada valley.

Abstract

The study investigated Dairy Co-operative Society as an information source in solving problems of the farmers in Haldwani and Bhimtal blocks of Nainital district. The study was carried out on a sample of 80 households, out of which, 44 belonged to member category and 36 to the non-member of Dairy Co-operative Society. The results showed that members' frequency of contact with milk Co-operatives, doctors and extension agents was significantly higher than that of nonmembers in both the plains and the hills. Highest proportion of information by members in both the areas was obtained from dairy co-operatives, however it was zero in non-members. Positive role of dairy Co-operatives in information dissemination was felt more by members than non-members in both the plains and hills. Hence enhancing the non-members' participation in DCS by providing appropriate incentives could benefit them in having a greater degree of accessibility to quality information.
