DISTRIBUTION OF NEPHELINE (ne) VALUES

Nepheline values reported in the 17 samples from Table Mountain range from 0.7% to 14.64%. with a median value of 8% to 12%. The Loss on Ignition (LOI) portion indicates that surface weathering has leached some of the nepheline content. Values are expected to be higher on fresh rock samples. No pattern emerged from the distribution of ne-values in the field. Sample #13 (ne 0.7%) was collected from a rock joint at the SE quarry. Its low value is attributed to excessive weathering. Bulk samples A and B were collected at the North quarry and SW quarry respectively. These samples came from the large quarried blocks that are less exposed to weather.
