Five uranium exploration cores from Lisbon Valley in the Paradox Basin of southeastern Utah provide examples of sedimentary structures and lithofacies from the Lower Permian Cutler Formation and the overlying Moss Back Member of the Upper Triassic Chinle Formation. The Cutler Formation consists of reddish-brown to purple, arkosic sandstone, siltstone, and mudstone of fluvial and floodplain origin interbedded with reddish-orange sandstone and mud-stone deposited in sabkha, eolian dune, and sand-sheet settings. The colors are indicative of the respective depositional settings. An erosional nconformity separates the top of the Cutler from the overlying Moss Back Member of the Chinle Formation. ...
"As someone who has spent forty years in psychology with a long-standing interest in evolution, I'll just assimilate Howard Bloom's accomplishment and my amazement."-DAVID SMILLIE, Visiting Professor of Zoology, Duke University In this extraordinary follow-up to the critically acclaimed The Lucifer Principle, Howard Bloom-one of today's preeminent thinkers-offers us a bold rewrite of the evolutionary saga. He shows how plants and animals (including humans) have evolved together as components of a worldwide learning machine. He describes the network of life on Earth as one that is, in fact, a "complex adaptive system," a global brain in which each of us plays a sometimes conscious, sometimes ...
To visiting geologists, Black Rock, New Mexico, is a basaltic escarpment and an ideal natural laboratory. To hospital workers, Black Rock is a picturesque place to earn a living. To the Zuni, the mesas, arroyos, and the rock itself are a stage on which the passion of their elders is relived. William A. Dodge explores how a shared sense of place evolves over time and through multiple cultures that claim the landscape. Through stories told over many generations, this landscape has given the Zuni an understanding of how they came to be in this world. More recently, paleogeographers have studied the rocks and landforms to better understand the world as it once was. Archaeologists have conducted ...
