项目摘要

An intensive archaeological survey has been conducted at the cave named "Sikkariabe Cave" (Abe Site), one of the six caves we have discovered since 2002 near Shiriyazaki Cape in the Shimokita Peninsula in northern Japan. In the excavation which has been performed three times since 2002,the survey area was gradually expanded and now reached up to a depth of approximately 2.5 m in about 16 m^2 range. Excavation was extremely difficult because the deposit in the cave contained a large quantity of angular limestone gravels of various sizes. Therefore, we adopted a method to dissolve all the excavated soil in water and to take out remains using a sieve.From this survey, we found that the upper layers (1^<st> and 2^<nd> layers) densely contained earthenware, stone implements, human bones and various animal remains, which appear to be the remains of the mid-end to early latter Jomon Period. It brought us valuable findings concerning hunting, fishing and interment rituals during the Jomon Period.In the latest survey, stone implements and animal remains were newly found from the 4^<th> layer existing below the upper layers (1^<st> and 2^<nd> layers), and also animal remains were discovered from the 12^<th> layer existing far below. Several stone implements that were unearthed from the 4^<th> layer included awls made of stone flakes. It is considered that they may belong to the very early days of the Jomon Period or the Plaeolithic Age. In addition, stone flakes that were produced when making gravers or bifacial points-belonging to the Plaeolithic Age-were newly discovered among the stone implements buried in the upper layers (1^<st> and 2^<nd> layers). From these results, it can be said that the possibility has increased that the remains of the Plaeolithic Age, the remains of extinct animals and human bones can be found together in this cave, if the survey area is further expanded around the 4^<th> and 12^<th> layers in the future survey.

自2002年以来，我们在日本北部Shimokita Peninsula的Shiriyazaki Cape附近发现的六个洞穴之一，在名为“ Sikkariabe Cave”的洞穴中进行了一项密集考古调查。在自2002年以来进行了三次的发掘中，调查区域逐渐扩展，现在在约16 m^2范围内达到了约2.5 m的深度。挖掘非常困难，因为洞穴中的沉积物包含大量各种尺寸的角石灰石砾石。因此，我们采用了一种方法来溶解水中所有发掘的土壤并使用筛子取出残留物。从这次调查中，我们发现上层（1^<st>和2^<nd>层）密集地含有陶器，石材的工具，人类骨头和各种动物遗体，这似乎是后端到后期乔蒙时期的遗骸。它为我们带来了有关乔蒙时期狩猎，钓鱼和葬礼仪式的宝贵发现。在最新的调查中，从上层下方存在的4^<th>层新发现了石材工具和动物遗体（1^<st>和2^<nd>层），还从以下的12^<th>层中发现了动物遗体。从4^<th>层发掘出的几块石材工具包括石片制成的锥子。据认为，它们可能属于乔蒙时期或普洛伊果石年龄的早期。此外，在埋在上层层中的石头上（1^<st>和2^<nd>层）中发现了新的石器时代时，生产的石片是生产的石片。从这些结果中可以说，可能性增加了普洛伊果石时代的残留物，如果在4^<th附近进一步扩展了调查区域，则可以在这个洞穴中一起发现灭绝的动物和人类骨骼的残留物。 >和12^<th>在将来的调查中。
