This form of Sphalerite is also known as "schalenblende". There are terrific photos on the Mindat page in which the schalenblende is described well. Basically the concentric zones of deposition vary in color and grain size and seen in the photos as light brownish yellow to dark brown rings. The outer margin is mostly Marcasite. Galena later infiltrated the host as seen by silvery blobs cutting all layers of former deposition.
