Nyman et al, 2006
Köppen climate type:
"Several mudrock-dominated Cenozoic (especially Miocene) sedimentary formations in the North Island of New Zealand include carbonate concretions having a wide range of tubular morphologies. The concretions are typically oriented at high angles to bedding, and often have a central conduit that is either empty or filled with late stage cements."(Nyman et al, 2006)
The central tubes of these concretions may contain a range of Ca-Mg carbonates and/or opaline silica or quartz.
