Site Identification of the GNSS Monument Site Name : Gaia Four Character ID : GAIA Monument Inscription : IERS DOMES Number : 13902M001 CDP Number : (A4) Monument Description : Pillar with a metal structure Height of the Monument : 2.476 m Monument Foundation : CONCRETE BLOCK Foundation Depth : 1 m Marker Description : (CHISELLED CROSS/DIVOT/BRASS NAIL/etc) Date Installed : 2000-01-02T12:00Z Geologic Characteristic : see additional information Bedrock Type : METAMORPHIC Bedrock Condition : WEATHERED Fracture Spacing : (0 cm/1-10 cm/11-50 cm/51-200 cm/over 200 cm) Fault zones nearby : No Distance/activity : (multiple lines) Additional Information : The GPS station is located on the : grounds of the Astronomic Observatory of : University of Porto at Monte da Virgem- : Vila Nova de Gaia.Monte da Virgem is a : granitic hill located on the left bank of : Douro River facing Oporto. The rock, an : alkaline granite,is Variscan in age : (upper Carboniferous,315 My old) and : belongs to the 'Granito do Porto' plutonic : body.The station is emplaced on a set of : outcrops that present close jointing. The : joints belong to 4 families that trend N50E, : N72E, N20W and N50W and are mostly vertical. : The spacing of the joints varies from 5 to : 40 cm. The rock is somewhat weathered. : Although it is on a flat platform close : to the 90-m high cliffs of Douro River : it is geologically stable. 2.
