The Lavernock Point magnetic, carbon isotope and chronostratigraphic datasets

These datasets includes the paleomagnetic, rock magnetic, carbon isotope datasets for the Lavernock Point sections. They also include the statistically constructed magnetochrons for the early Rhaetian, and the statistical evaluation of the comparisons between the biostratigraphic GPTS and key comparable sections in the Sevatian and early Rhaetian. The datasets include the following pages of information housed in excel spreadsheets: Raw palaeomagnetic measurementsAll NRM intensity (J0) and magnetic susceptibility dataField correctionsDirectional analysis on all the Lavernock specimens, and sample means Organic carbon isotope datasets (and % total carbon and nitrogen)Rotational remanent magnetisation measurementsWorkings for the statistical composite polarity constructionReference magnetostratigraphic scalesSevatian-Early Rhaetian correlation model statisticsR-script used for creating the matrix correlation statistics本数据集涵盖拉弗诺克角（Lavernock Point）剖面的古地磁、岩石磁学与碳同位素数据集。同时包含针对早瑞替期的统计构建地磁极性年表（magnetochrons），以及对塞瓦阶（Sevatian）与早瑞替期内生物地层学地磁极性时间尺度（Geomagnetic Polarity Time Scale, GPTS）与关键对比剖面之间的对比结果开展的统计评估。 本数据集包含以下存储于Excel电子表格中的信息条目： 1. 原始古地磁测量数据 2. 所有天然剩余磁化强度（Natural Remanent Magnetization, NRM）强度（J₀）与磁化率数据 3. 野外校正数据 4. 针对所有拉弗诺克角标本的方向分析结果及样本均值 5. 有机碳同位素数据集（及总碳、总氮百分含量数据） 6. 旋转剩余磁化强度测量数据 7. 统计复合极性构建的运算过程文件 8. 标准地磁地层学标尺 9. 塞瓦阶-早瑞替阶对比模型统计结果 10. 用于构建矩阵相关统计的R脚本（R-script）
