Site Identification of the GNSS Monument Site Name : O'Higgins / Antarctica Four Character ID : OHIX Monument Inscription : Pillar K3 IERS DOMES Number : 66008M006 CDP Number : Monument Description : PILLAR Height of the Monument : 1.4 Monument Foundation : CONCRETE PILLAR BOLTED ON BEDROCK Foundation Depth : 0.5 Marker Description : SURVEY MARKER WITH THREAD Date Installed : 2002-02-07T00:00Z Geologic Characteristic : Bedrock Bedrock Type : Metamorphic Bedrock Condition : Weathered Fracture Spacing : 50-200 cm Fault zones nearby : (YES/NO/Name of the zone) Distance/activity : (multiple lines) 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 antenna : is bolted into one of these veins, : which are very resistant to weathering. : OHIX and OHI3 are operating with the : same antenna, on Pillar K 3, IERS DOMES : Number 66008M006 . 2.
