The Intensely Bored Rocks in Vinjhan (Kutch) Indicate Glossifungites Ichnofacies

The occurrence of Glossifungites ichnofacies from the Vinjhanian stage exposed near Vinjhan in Kutch have confirmed its development of the firm but unlithified substrates possibly intertidal to subtidal in nature where the semi consolidated substrate provided resistance to erosion and supported three generations of borings by different organisms. The filling of the borings with gypsum and development of iron-oxide stains on them indicate a major regressive phase of the Vinjhanian stage and diagenetic effects due to chemical variations in the depositional system.
