Dec 07, 2005 (A Wilson) - The Cradle Lakes Deformation Zone is at least 5 km in length and rouchly 1-2 km wide, but may be up to 10 km in total length. The CLDZ is subparalle to stratigraphy and occurs largely within fedlspar-crystal tuffs, which in many places are difficult to distinguish fromthe cradle Lakes stock, a feldspar porphyry intrusion adjacent to and partially within the CLDZ. The CLDZ contains a large, east-striking high stain zone that is up to 40 m wide and has been traced for several hundred metres along strike.
