Site Identification of the GNSS Monument Site Name : O'Higgins / Antarctica Nine Character ID : OHIG00ATA Monument Inscription : Pillar K5 IERS DOMES Number : 66008M001 CDP Number : Monument Description : PILLAR Height of the Monument : Monument Foundation : Foundation Depth : Marker Description : Date Installed : 1995-02-14T00:00Z Geologic Characteristic : BEDROCK Bedrock Type : METAMORPHIC Bedrock Condition : WEATHERED Fracture Spacing : 50-200 cm Fault zones nearby : Distance/activity : Additional Information : Predominant rocks at the station : O'Higgins are quartz-bearing black, : grey and reddish brown : low-metamorphic clay slates and : phylitte slates of the Trinity : Peninsula Formation. They are very : brittle, fine-laminated in the mm- : and cm-range and incline with about : 60 to 80 degrees to NW. : Because of these characteristics : and the high clay mineral content : and the expansive force resulting : from this the slates are highly : susceptible to weathering and mostly : covered by detrital layers. Only : tectonicly less stressed parts and : parts resistant to weathering stick : out from these detrital masses. These : have a linear geometry and show strong : cleavings. The instrusions of 0.5m to : 1.5m thick vein rocks, which pass : through the slates, are significantly : younger. The pillar with the Turbo : Rogue antenna is bolted into one of : these veins, which are very resistant : to weathering. : A ROGUE SNR-8000 operates since : 14-FEB-1995 at the ERS/VLBI- Station : O'Higgins. : Upgrading Firmware firmware from V 3.0 2.
