Absolutely yes! Many of the rocks in the Himalaya are limestones from sediments on the bottom of the (recently closed) Tethys Ocean. The karst is generally "immature" in that at the high cold altitudes, there has not yet been much dissolution of the relatively young limestone. Rocks that are older and/or in warmer climates tend to be more karstified. There is a large cave near Pokhara, Nepal.
