Notes - 4

• HDPH is used to record information regarding exploratory hole construction. The HDPH group subdivides the hole development by depth such that the differing methods used to advance a hole or pit (or holes developed using combined methods) are explicitly described As a minimum, one record will exist in HDPH for each record in the LOCA group if the AGS file is transferring hole construction details.
• Records of orientation and inclination of the exploratory hole should be included in the HORN group.
• Records in HDPH should be continuous and non-overlapping.
• HDPH_LOG and HDPH_LOGD have been added to include the name of the person describing the strata in this section of the exploratory hole and date as required in ISO 14688-1 (Section 6) and EN ISO 14689-1 (Section 5). It is not deemed necessary to detail this information further for example in the GEOL group.
