Abstract An improved Lamoureux method for subsampling of unconsolidated laminated sediment is described. Here, we describe a new methodological approach that changes the Lamoureux method in four steps of which the most important change concerns dehydration and stabilization. In this step, we adopted gypsum embedding of the subsample, which took about 1 h to harden and keeps the sediment partially moist. After drying of the gypsum, the subsamples are impregnated with Epoxy 2000 resin under room temperature. This method requires commonly available equipment and can be implemented cost-effectively within 3–4 days.

用石膏制备薄片对松散层状湖泊沉积物的脱水和稳定

摘要 描述了一种改进的 Lamoureux 方法，用于对松散层状沉积物进行二次采样。在这里，我们描述了一种新的方法论方法，该方法在四个步骤中改变了 Lamoureux 方法，其中最重要的变化涉及脱水和稳定。在这一步中，我们采用石膏嵌入子样品，大约需要 1 小时才能硬化并保持沉积物部分湿润。石膏干燥后，在室温下用环氧树脂 2000 树脂浸渍子样品。这种方法需要常用的设备，并且可以在 3-4 天内经济高效地实施。
