Identification of limestone type
Limestones are usually categorized following the Dunham &amp; Folk classification. Only very rare or special limestones were given a name and these are often named after the location where they can be found e.g. Travertine. 

The images you provided are not very explicit which makes it literally impossible to clearly identify the limestone. Please consider next time to upload close up pictures that show the composition e.g. bioclasts and cements of the limestone. 

However, there is a paper by the Geological Society of India were the authors date a limestone from the Jammu region which they refer to as Jammu limestone or Great limestone. The authors suggest that the limestones are from the Precambrian due to stromatolites that were found there in. 

I hope this helps!
