Martley Rock Temporary Trenches

Finally, a month after the dig on 2nd Sept., some pictures of the amazing, spectacular, multi-coloured excavations at Martley Rock field, kind permission of Helen and Rob Taylor of Cob House Fisheries, all on a glorious early Autumn day in the driest September (it turned out) on record. Whew. A day not to forget for those there, with every bucketful revealing more and often surprising features of the rocks just under the surface soil. Of course by now we know about the 5 (or is it six?) geological periods in the field, but we didn’t know about the quartzite reef that bisected one trench, nor the direction of the East Malvern fault at the North end of the field as it dived under the hedge and across Kingswood lane.  The pattern of the formations and the discovery of new fault lines add evidence of a giant, million year mix, the presence of copper ore (azurite, bright turquoise) in small quantities (a sometime feature of magmatic rocks such as the Malvern Complex granites), never seen here before. Wonderful.  Some pictures (there are hundreds more)
