1. Site Identification of the GNSS Monument
Site Name : Gaia
Nine Character ID : GAIA00PRT
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.
