广西大厂泥盆系浊积岩主要见于中泥盆统，具明显的鲍玛序列，其组分由跳跃和悬浮两部分组成，堆积速率为（5．1～38．5）×10－4m／a。硅质岩主要见于上泥盆统，其中发现有海底火山热液活动的喷口，通过所含铁闪锌矿FeS的含量分析计算，其形成压力为0、267×108Pa，相当于2670m水深。所有特征表明它们是在深水裂谷盆地背景下，由于浊流沉积和热水沉积而形成的，是大厂热液成因超大型块状硫化物矿床和生物礁油气藏重要的标志。
The Devonian turbidites in Dachang, Guangxi Province are mainly found in the Middle Devonian with obvious Bowman sequences. The components of the turbidites consist of two parts: leaping and levitation, and the accumulation rate is (5.1 ~ 38.5) × 10-4m / A. The chert is mainly found in the Upper Devonian, in which a spout of hydrothermal activity of the submarine volcano is found. Based on the analysis of the content of iron-zinc blende FeS, the forming pressure is 0,267 × 10 8 Pa, equivalent to 2670 m of water depth. All the features indicate that they are formed in the background of deep-water rift basins due to turbidite flow and hydrothermal sedimentation, and they are important marks of Dachang hydrothermal formation super massive massive sulfide deposits and bio-reef reservoirs.
