While old trees are generally acknowledged for a long carbon residence time, there is no consensus on their contribution to carbon accumulation due to a lack of long-term individual tree data.

Porosity measurements of Wisconsin rocks. The porosities of the rocks measured vary from 2% to more than 30%.Much of this variation is due to lithology (rock type). The data table lists the porosities of the tested samples and the figure at right shows the range and distribution of porosities by lithology. The dolomites have the lowest porosities (2–6%), the shales have the …

· Gordondale samples enriched with carbonate (calcite and dolomite) typically have lower total porosities than carbonate-poor rocks and hence have lower potential free gas contents. On a regional reservoir scale, a large proportion of the Gordondale total gas capacity is free gas storage (intergranular porosity), ranging from –22 Bcf/section (– m 3 /section).
Many cements are reactive and easily chemically weathered, iron oxide and calcite. Sedimentary rocks with very weak cementation, boulder clay, gravels and sands, are termed unconsolidated. Igneous rocks, granite, and metamorphic rocks, marble, are crystalline with strong chemical bonding. Rocky coastlines vary in resistance of geology. Granite erodes …
