GB Cave (grid reference ST47595623) is a cave near Shipham in the limestone of the Mendip Hills, in Somerset, England. A geographic coordinate system enables every location on the Earth to be specified in three coordinates using mainly a spherical coordinate system. A geographic coordinate system enables every location on the Earth to be specified in three coordinates using mainly a spherical coordinate system. The British national grid reference system is a system of geographic grid references commonly used in Great Britain, different from using Latitude and Longitude Shipham ( is a village in Somerset, England on the western edge of the Mendip Hills near the A38, approximately 15 miles south of Bristol The Mendip Hills (commonly called The Mendips) are a range of Limestone hills situated to the south of Bristol and Bath in Somerset Somerset ( or) is a county in south west England The County town is Taunton, which is in the south of the county England is a Country which is part of the United Kingdom.

GB Cave is 1. 95 km (6,400 ft) in length and reaches a depth of 134 m (440 ft). [2] It is named after Francis Goddard and Charles Barker who first discovered it in 1939. [3] GB Cave is remarkable for the Gorge, a passage large enough to contain several double-decker buses, and the main chamber which is the largest cavern amongst the Caves of the Mendip Hills. A double-decker bus is a Bus that has two levels While double-decker long-distance coaches are in widespread use around the world double-decker city buses are The Caves of the Mendip Hills are formed by the particular geology of the Mendip Hills, with large areas of limestone worn away by water makes it a national centre for Caving
The trace elements Magnesium, Strontium and Barium have been found by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) from three Holocene speleothems taken from Great Chamber in GB Cave. Magnesium (mægˈniːziəm is a Chemical element with the symbol Mg, Atomic number 12 Atomic weight 24 Strontium (ˈstrɒntiəm /ˈstrɒnʃiəm/) is a Chemical element with the symbol Sr and the Atomic number 38 Barium (ˈbɛəriəm is a Chemical element. It has the symbol Ba, and Atomic number 56 Mass spectrometry is an analytical technique that identifies the chemical composition of a compound or sample based on the Mass-to-charge ratio of charged particles The Holocene is a Geological epoch which began approximately 10000 years ago (about 8000 BC A speleothem (from the Greek for "cave deposit" commonly known as a cave formation, is a secondary mineral deposit formed in a Cave.
