ACEVEDO, Rogelio Daniel y GONZALEZ-GUILLOT, Mauricio. First petrophysical trials over dimension stones of Tierra del Fuego. Rev. Asoc. Geol. Argent. [online]. 2011, vol.68, n.2, pp.233-245. ISSN 0004-4822.
These are the first trials in laboratory over dimension stones of Tierra del Fuego. The Fuegian territory had a not evaluated potential respect of the possible use of this native resource. Neither hard rocks nor metamorphic rocks (slates) have been applied ever for residential construction, facades and flooring in Fuegian buildings until now. Only in recent years, two little quarries of plutonic rocks have been opened. One of them in the Jeu-Jepen hill, worked firstly to build the breakwaves of Río Grande harbour and then the National railroad. The other one is located in the Ushuaia Peninsula and was started initially to remove a hill for locate the airport and lately used for facings. In the present work, selected stone samples were analysed under standard ASTM test methods for determining compressional strength and modulus of rupture, practiced in accord to IRAM specification for determining apparent density, water absorption and open porosity and Dorry hardness test for measuring the resistance to abrasion. In Isla Grande of Tierra del Fuego the major types of dimension rocks are scarce and randomly distributed granitic bodies, any of them with relatively high compressional and tensional resistance. Therefore, the analyzed rocks of the Jeu-Jepén hill combine among others the best conditions for its immediate use: high petrophysical responses, possibility of obtaining useful-sized blocks, open quarry and easy access.
