它们是在chwyza和ds之间的高速公路、活动区域和滑动区域。“eG utschb山脊”(瑞士坐标:6 90'314/211'943;在1979年至1981年期间，《施皮格伯格》(Spiegelberg)和《施皮格伯格》(Spiegelberg)的作品都采用了基于矩阵的版本。他说:“我们发现了一种新的发现，即在地球表面以下2.5米和3.8米的地层中，我们发现了一种新的发现，即在地球表面以下2.5米和3.8米的地层中，我们发现了大量的样品。”岩石的表面。在地基的基础上，每个地基的地面高度为40mb。“新样品”(均为“P - inus - sylvestris”)测得的放射性碳含量在1.690-11.270 cal. a BP (2s)之间，与格林兰传统的“1”(GS-1;“young - gerd ryas”)的碳含量在1.3.830 -13.640 cal. a BP (2s)之间。“它是在interstadial I-1c”(格陵兰“interstadial I-1c”;“Alleroed”)，“尤其是”。他说:“这一结果表明，伊拉克的不稳定局势已经开始，伊拉克的天然气储备已经开始减少，伊拉克的天然气储备已经开始减少，伊拉克的天然气储备已经开始减少。”“我们的研究结果表明，相比于其他类型的订单，在g -1和g -1(即“egelseeo振荡”)和g -1之后不久，p -1就会出现“更大的波动”。
