The Bulgarian prehistoric sequence is characterized by the use of particular raw materials in distinct ‘cultural’ contexts. The Karanovo I and II stages of the Early Neolithic (part of a supra-regional technocomplex in the Balkans) are recognisable by formal toolkits made of Balkan flint. The Chalcolithic period is famous for its superblades made of high-quality Ludogorie flint, which also attain a wider Balkan distribution. Despite a solid corpus of reliable data for northern Bulgaria from our previous field surveys and laboratory analyses, there are still questions that can only be resolved by further research.

This paper presents the results of petrographic and chemical (LA-ICP-MS) analyses of a series of archaeological artefacts and raw material samples collected during a survey in Shumen District of northeast Bulgaria. These data allow us to i) distinguish two new types of flint (Shumen I and II) which are represented by both raw material outcrops and artefacts and previously referred to as ‘Moesian flint’; and ii) expand our analytical data for the Kriva Reka type of Ludogorie flint, confirming its substantial role in prehistoric flint production, distribution and use. These results suggest a more complex network of raw material sources and distribution routes in prehistory than previously assumed.

保加利亚史前序列的特点是在不同的“文化”背景下使用特定的原材料。新石器时代早期的 Karanovo I 和 II 阶段（巴尔干地区超区域技术综合体的一部分）可以通过由巴尔干燧石制成的正式工具包来识别。铜石器时代以其由高品质 Ludogorie 燧石制成的超级刀片而闻名，这些产品在巴尔干地区的分布范围也更广。尽管我们之前的实地调查和实验室分析为保加利亚北部提供了可靠的可靠数据，但仍有一些问题只能通过进一步的研究来解决。

本文介绍了在保加利亚东北部舒门区调查期间收集的一系列考古文物和原材料样品的岩相学和化学 (LA-ICP-MS) 分析结果。这些数据使我们能够 i) 区分两种新类型的燧石（舒门 I 和 II），它们以原材料露头和人工制品为代表，以前称为“莫斯燧石”；ii) 扩展我们对 Kriva Reka 类型的 Ludogorie 燧石的分析数据，确认其在史前燧石生产、分配和使用中的重要作用。这些结果表明史前原材料来源和分销路线的网络比以前假设的更复杂。
