  • Pressure Is Of The Essence (Intro)

    An Inquiry Into Time, Pressure, Structure And Formation Introduction We are accustomed to describing the history of the Earth in terms of time. Millions of years. Hundreds of millions of years. Billions of years. Geological ages become the framework through which we interpret mountains, minerals, fossils, coal, petroleum, crystals, sediments and transformations of the deep…

  • What Do We Mean by Pressure? (Preamble)

    What Produces It,How It Acts AndWhat It Can Produce What is Pressure? Before pressure can be tested as a formative variable, it must be defined carefully. Pressure is not a substance and it is not an independent source of energy. In its simplest mechanical definition, pressure is force distributed over area. But that definition does…

  • Mineral Hydration, Clay Formation And Lithification (1)

    Candidate One What the Laboratory Clock Actually Measures The Question The investigation began with a simple question: How much time has actually been demonstrated to be physically necessary for clay-rich material to form, transform, compact, cement and become rock? The research protocol required that chronological assignments be separated from directly measured formation rates. Geological formations…

  • Diamond Formation And Mantle Inclusions (2)

    Candidate Two What the Laboratory Clock Actually Measures The Question The investigation began with the same discipline established in Domain 1: How much elapsed time has actually been demonstrated to be physically necessary for carbon to become genuine crystalline diamond? The inquiry separates formation duration from chronological age assignment. A diamond may be assigned an…

  • Metamorphism And Orogenesis (3A)

    Rapid SedimentationAnd Rapid Erosion A Measurement-First Examination ofGeological Process Purpose This investigation asks no chronological question. It examines what sediment and rock demonstrably do under measured physical conditions. Where a process can be observed, reproduced, measured or identified structurally, that process is reported without attaching an age to it. The purpose is not to defend…

  • Metamorphism (3B)

    The Two Laboratories Metamorphism Metamorphism is the solid-state reorganization of an existing rock through changes in its mineral structure, texture, chemistry or internal arrangement without wholesale melting. The starting material may be sedimentary, igneous or already metamorphic. Under suitable physical conditions, existing minerals may disappear, new minerals may grow, grains may recrystallize, crystal structures may…

  • Orogenesis (3C)

    The Mountain Is The Measurement Orogenesis Orogenesis is the large-scale deformation and structural reorganization of Earth material associated with the formation of mountain systems. It includes uplift, crustal thickening, folding, faulting, thrusting, stacking, deformation, exhumation and the movement of rocks from one pressure-temperature environment into another. Domain 3B established metamorphism as a condition-dependent transformation of…

  • Mineral Hydration And Clay Formation (4)

    Reaction Time And The Geological Clock Mineral Hydration and Clay Formation Clay formation is a mineral and chemical transformation, not merely the mechanical production of very small rock particles. Clay minerals possess characteristic crystal structures and compositions. Their formation may involve dissolution of a parent mineral, transport of dissolved constituents through fluid, nucleation and precipitation…

  • Fossilization And Sedimentary Preservation (5)

    The Race Between Destruction And Preservation Fossilization and Preservation Fossilization is not a single process. Biological remains may be preserved through permineralization, replacement, phosphatization, pyritization, silicification, carbonization, recrystallization, molds and casts or exceptional retention of original resistant material. These pathways differ chemically, but they confront the same immediate physical problem: after death, biological structure begins…

  • Petroleum And Hydrocarbon Generation (6)

    The Experiment Is The Whole Environment Petroleum Petroleum is a naturally occurring mixture composed principally of hydrocarbons found within Earth. The word comes from Latin terms meaning rock and oil, literally, rock oil. Petroleum is not one chemical substance. Crude oil contains many different hydrocarbon molecules together with smaller quantities of compounds containing sulfur, nitrogen,…
