What stones often appear on the sand? ——Hot topics and geological exploration in the entire network for the past 10 days
Recently, "the composition of stones in the sand" has become a hot topic on social platforms, and netizens have shared their strange stones found in beaches, deserts or building sand. This article combines hot spot data on the entire network for nearly 10 days to analyze common stone types in sand and their causes of formation, and attaches structured data analysis.
1. Background of popular topics across the Internet
According to monitoring, the number of discussions on "picking stones from sand" on platforms such as Douyin, Weibo and Xiaohongshu increased by 120% month-on-month. The following is the hottest ranking of related topics in the past 10 days:
| Ranking | Topic keywords | Popularity index | Main Platforms |
|---|---|---|---|
| 1 | Picking transparent stones in the desert | 95,000 | Tik Tok |
| 2 | Beach pebbles | 72,000 | Little Red Book |
| 3 | Construction sand containing quartz | 58,000 | Zhihu |
2. Common types of stones in sand
Geological studies show that most of the stones in sand are the following five categories:
| Stone type | Percentage | feature | Causes of formation |
|---|---|---|---|
| quartz | 60%-70% | Transparent/transparent, high hardness | Weathered granite residue |
| Feldstone | 10%-15% | Pink/white, shattered | Volcanic rock decomposition products |
| Basalt chips | 5%-8% | Black, porous | Erosion after volcanic eruption |
| Shell fossil | 3%-5% | White stripes with smooth surface | Marine biodeposit |
| magnetite | ＜1% | Metallic luster, adsorbable magnet | Crystallization of magma |
3. Netizens discovered cases on the spot
According to the statistics of 200 samples uploaded by Xiaohongshu users:
| Discovery location | High frequency stone | Probability of occurrence |
|---|---|---|
| Sanya Beach, Hainan | Coral fragments | 89% |
| Takramakan Desert, Xinjiang | Wind-ridged stone | 76% |
| River sand in the middle and lower reaches of the Yangtze River | Agate raw stone | 12% |
4. Experts interpret hot phenomena
Professor Li from China University of Geosciences analyzed:"Recently high temperature weather accelerates rock weathering, resulting in more mineral particles being exposed. Especially in desert areas, the temperature difference between day and night has increased the efficiency of rock disintegration by 40%, which is the main reason for the increase in the number of transparent quartz stones."
5. Practical Stone Picking Guide
1.Time selection: More new exposed stones within 24 hours after heavy rain or strong wind
2.Tool preparation: 10x magnifying glass, magnet, hardness test pen
3.Safety Tips: Avoid collecting radioactive minerals (such as monoliths), and wear gloves
Through the data in this article, it can be seen that the stones in the sand are not only a witness to geological evolution, but also a fun carrier for the whole nation to explore nature. Next time you encounter a sand pile, you might as well look down at the mineral treasures that may be hidden under your feet!
