Abstract:
The equation, N = 2-pi-x2/square-root 3, has been derived to find out the number of hexagonally distributed points (N), in a given circle of radius 'R' and the point-point distance 'd', where x = R/d. For a given set of microscopic conditions, the above equation is applied to construct 4 standard circular graphic charts. An attempt has been made to use these charts to study the population of fluid inclusions, by visual comparison, in the quartz samples intimately associated with the sulphides collected from the Mosaboni mine of Bihar.
