Fig. 2.From: Environmental magnetic record of the fluvial sediments from the Tianzhu borehole in Beijing for the last 800 kaOrthogonal projections of progressive alternative demagnetization data for the representative samples of the Tianzhu borehole. Solid (open) circles refer to the projection on the horizontal (vertical) plane. The depth of each sample is indicated. Demagnetized steps T350 and M38 refer to thermal demagnetization (°C) and alternating demagnetization (milli-Tesla), respectively.Back to article page
