A locality near Myponga Beach which has nodules of goyazite in Cambrian Heatherdale Shale. The occurrence of goyazite was described in Abele and McGowran (1958). The nodules are exposed on a wave cut platform NW of Black Hill and most are less than 3 cm across. The majority of the black nodules are apatite (with possible lesser goyazite), however as noted in Abele and McGowran "Red nodules occur in this area in a six-foot band several feet below the contact with Tertiary limestones. These contain hematite and goyazite (determined by Dr. Brian Skinner) as well as apatite."
My (B. Grguric) examination of the these nodules in-situ did not indicate they contained vughs lined with crystals but appear to be fine-grained admixtures of the minerals described above. This was later confirmed using SEM-EDAX analysis of polished nodules. The red nodules contain goyazite, clay and hematite. The dark nodules contain Sr-bearing apatite (Sr content 5.8 to 6.3 wt.%), quartz grains, sericite flakes and minor Fe-oxides. The images identified as goyazite from the Judy Rowe collection are suspect as far as this exact locality is concerned. They may have come from a nearby phosphate quarry.
