一、铷—锶法地质年龄计算公式: (公式)上式为一形式 y=a+bx 的直线方程比,可用最小二乘法回归分析求解.二、沉积作用模式年龄探讨基本原理及计算公式:全岩中锶的演化不受变质作用的干扰,为一连续的增长直线,依据测试得到变质作用年龄ti、初始锶? ti及估计沉积时海水锶?to求沉积作吊的模式年龄:?三、LAKR BL-701~c型计算器运算程序.四、沉积模式年龄计算结果分析:计算求得广平前泥盆系变质岩沉积作用模式年龄563—573m·y,与呆获檄体古植物化石及地质推断吻合.
First, the rubidium - strontium geological age calculation formula: (Formula) The above formula is a form of y = a + bx linear equation ratio, can be used least square regression analysis to solve. Second, the sedimentary mode of age to explore the basic principles and formulas: The evolution of strontium in the whole rock is not disturbed by the metamorphism and is a continuous growth line. According to the age of metamorphism, the initial strontium? Ti and the seawater strontium? , LAKR BL-701 ~ c calculator calculation program. IV. ANALYSIS OF AGE CALCULATION OF THE SEDIMENTARY MODEL: The sedimentary model of the Devonian metamorphic rocks in the Guangping area was calculated to be 563-573m · y, Fossils and geological inferred.
