Thomas Fischer 2023-06-08 UPDATE O'Higgins / Antarctica OHI3 Pillar K3 66008M006 PILLAR 1.4 CONCRETE PILLAR BOLTED ON BEDROCK 0.5 SURVEY MARKER WITH THREAD 2002-02-07T00:00:00Z Bedrock METAMORPHIC WEATHERED 51-200 cm 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. An ASHTECH Z18 GPS+GLONASS operated from 2001-02-09 until 2003-01-27 at the ERS/VLBI-Station GARS O'Higgins / Antarctica with the four character ID OHIZ, DOMES Number 66008M004. Because of the expansion and of construction works in the Chilenean Antarctic Base the antenna for the GPS+GLONASS Permanent Tracking Station OHIZ was moved to another pillar K3, DOMES Number 66008M006.

In addition and parallel also a ROGUE SNR-8000 / ACT SNR-8000 ACT operated from 1995-02-14 until 2002-02-20 at the ERS/VLBI- Station GARS O'Higgins / Antarctica with the four character ID OHIG, on pillar K5, DOMES Number 66008M001.
