Abstract

Two contiguous, but spatially separated occurrences of nepheline syenites in the northeastern part of Puruliya district, one having biotite as the principal mafic component and the other having amphibole with subordinate biotite as mafic minerals are studied. Although modal mineralogy of nepheline syenites of these two bodies contrasts considerably, bulk chemical compositions of them remain almost same. Petrographic features give evidences of metamorphism. It is Inferred that regional metamorphism of biotite-bearing nepheline syenite under granulite facies condition caused the appearance of amphibole-Bearing nepheline syenite. During this metamorphic transition, possible reactions between minerals are also drawn.

Abstract

Investigations were carried out to study the women engaged in different fishery management practices and to identify independent variables, which are related with the dependent variables, viz., decision making and supervision of women in fish culture in Dakshin Dinajpur district of West Bengal. Randomly selected 120 fisherwomen revealed that majority of them participate in different management practices like application of mohua oil cake (70%), liming (87.5%), application of organic manure (89.16%), and application of inorganic fertilizers (62.5%) and regular netting operation (82.5%). The findings revealed that out of twelve variables only six variables, namely, age, area of the ponds, education, family educational status, economic status and aspiration were significantly correlated with decision making process of women in fish culture. The findings also revealed that out of twelve variables only three variables, namely, age, economic status and aspiration were significant at 0.01 level of probability.
