Important advance are made in the date of slices and superslices:(1) Abundant acritarch and a few radiolarian fossils are collected in the "barren strata" formed by epi-middle metamorphic slices at Gouli, Longshigenggongwu, thus provide data evidence for this set of strata. A series of isotopic dating data (14) showed that the date are between 1 000 Ma and 500 Ma, close to that of the fossils.

在岩片和超岩片时态调查方面取得如下重要进展：(1)在沟里、龙什更公坞等地区的由中浅变质岩岩片构成的"哑地层"中获取较丰富的疑源类和少量放射虫化石，使该套地层从化石方面首次获得了确切的时代证据，并新获一大批同位素年龄数据（14个），年龄值主要分布在1000—500Ma之间，化石时代与同位素测年吻合较好。

Schist, a metamorphic rock, contains mineral crystals that can be seen by the naked eye.

Firstly, triaxial compression creep tests with mica-quartzose schist which is a kind of soft metamorphic rock with lots of schistosity surfaces were carried out on the rock servo-controlling rheology testing machine under the condition of the axial stress vertical to the direction of the schistosity surface.

首先，对片理发育的软弱变质岩—云母石英片岩，在轴向力与片理垂直的条件下，采用岩石全自动流变伺服仪进行了三轴压缩蠕变试验，对轴向蠕变和径向蠕变进行了对比分析，提出径向蠕变比轴向蠕变敏感，以径向蠕变长期强度作为长期强度更合理。
