The oldest (Carnian-age) formations of the Chinle Group (Zuni Mountains and Shinarump Formations) contain kaolinitic paleosols that display gley features but generally lack calcretes. Paleosols of the (Upper Carnian) Blue Mesa Member of the Petrifi ed Forest Formation are mostly mature Alfi sols that have distinctive horizonat...

A simple single-feeding circular polarization (CP) antenna with controlled left/right-hand characteristics is proposed and investigated for GPS L2 band applications. To achieve the CP characteristics, four arc-shaped cutting corners different sizes are removed from a patch to give 90∘ phase difference implement CP. By adjusting radius of corners, can be get (L/RHCP). The modeled, simulated, fab...
