BUNTER , the name applied by See also:

English geologists to the See also:lower See also:stage or subdivision of the Triassic rocks in the See also:United See also:Kingdom. The name has been adapted from the See also:German Buntsandstein, Der bunte Sandstein, for it was in See also:Germany that this See also:continental type of Triassic See also:deposit was first carefully studied. In See also:France, the Bunter is known as the Gres bigarre. In See also:northern and central Germany, in the Harz, Thuringia and See also:Hesse, the Bunter is usually conformable with the underlying See also:Permian formation; in the See also:south-See also:west and west, however, it transgresses on to older rocks, on to See also:Coal See also:Measures near Saarbruck, and upon the crystalline See also:schists of See also:Odenwald and the See also:Black See also:Forest. The German subdivisions of the Bunter are as follows;—(1) Upper Buntsandstein, or Rot, mottled red and See also:green marls and See also:clays with occasional beds of shale, See also:sandstone, See also:gypsum, rocksalt and See also:dolomite. In Hesse and Thuringia, a quartzitic sandstone prevails in the lower See also:part. The " Rhizocoralhum Dolomite " (R. Jenense, probably a sponge) of the latter See also:district contains the only Bunter See also:fauna of any importance. In See also:Lorraine and the See also:Eifel and See also:Saar districts there are micaceous clays and sandstones with plant remains—the Voltsia sandstone.
