More model informationThe Moeraki boulders are large (to 2 m) calcite concretions with septarian veins of calcite and rare late-stage quartz and ferrous dolomite. The concretions are enclosed by Paleocene marine mudstones. The greatest concentration of concretions occurs on the beach near Moeraki in a region of active seaward-directed mass movement, where wave erosion has removed the mudstone matrix, leaving a lag of large concretions.
