山东寿光双王城盐业遗址群是2008年度全国十大考古新发现,全国重点文物保护单位。014A遗址是双王城遗址群中的一个完整的商周时期制盐作坊单元。为进一步了解当时的盐业生产流程,采用XRF、XRD和有机碳分析等科技手段,对01 4A遗址不同位置的土样进行了测试。从土样中各成分的变化趋势可以看出,南部坑池1上游应为卤水的沉淀池,下游和坑池2应为蒸发池,与考古学者推测的盐业生产流程相一致。同时,研究表明遗址中分布的灰绿色土有机质含量偏高,可能跟坑池中的“藻垫”有关,从而表明我国先民早在商代就发现了藻垫生长具有防止卤水渗漏的作用,并能够有意识地加以利用,说明当时的制盐工艺已经达到了相当高的水平。
Shandong Shouguang Shuangwangcheng salt site is the 2008 National Top Ten archaeological discoveries, the national key cultural relics protection units. The site of 014A is a complete Shang Zhou period salt workshop unit in Shuangwangcheng site. In order to understand the current salt production process at the time, XRF, XRD and organic carbon analysis were used to test the soil samples in different locations of 01 4A site. It can be seen from the changing trend of each component in soil samples that the upstream of Hangchi 1 in the south should be a sedimentation tank of brine and the downstream and pit 2 should be an evaporation pond which is consistent with archeologists’ salt production process. At the same time, the study shows that the content of organic matter in the gray-green soil distributed in the site is high, which may be related to the “algae mat” in the pit, which indicates that our ancestors discovered the algal mat growth as early as the Shang Dynasty, The role and can be used consciously, indicating that the salt making process has reached a very high level.
