Led by Dr. Lü Guo, Suntrans provided English proofreading services for the book *Earth Science Frontiers*

Dr. Lyu Guo, Chairman of Beijing Suntrans, participated in the English proofreading work for this publication of Earth Science Frontiers. The detailed information is as follows:

Ophiolites, as fragments of ancient oceanic crust and upper mantle occurring at active continental margins, record information on oceanic lithospheric dynamics and geotectonics during the evolution of ancient ocean basins, and serve as an important basis for studying the processes of continental block accretion and ocean-continent evolution [1-5]. Ophiolites were initially thought to form at mid-ocean ridges (MORs); however, with the in-depth development of research, they can also form in subduction zone environments. Corresponding to trench-arc-basin systems, ophiolites may occur in fore-arc, island arc, and back-arc settings [6-7]. As a key component of ophiolites, mantle peridotites have undergone mantle melting processes and subsequent reactions with fluids/melts, which makes them of great significance for investigating the evolution of oceanic lithosphere [80]. The Qinghai-Tibet Plateau is a typical global continental collision orogenic belt that has experienced long-term tectonic evolution, with several giant ophiolite belts distributed across it [10-14]. The Yarlung Zangbo Ophiolite Belt, situated in the southern part of the Qinghai-Tibet Plateau, acts as a critical boundary between the Indian Plate and the Eurasian Plate, representing the remnants of the Neo-Tethyan Ocean Basin [15-17]. As an important part of the Yarlung Zangbo Suture Zone, the Shigatse Ophiolite has long been a research hotspot. Early researchers conducted studies on different units of this ophiolite from various perspectives; however, there remains considerable controversy regarding its genesis and tectonic setting, which is mainly categorized into three viewpoints: mid-ocean ridge (MOR) type, initial oceanic basin type, and subduction (SSZ, Supra-Subduction Zone) type. In recent years, with the advancement of further research on the Shigatse Ophiolite, the MOR type can be further subdivided into normal mid-ocean ridge type and late oceanic mid-ridge type based on the characteristics of ophiolite fragments exposed in different areas [3]; in terms of the features of different basic rocks within the ophiolite, it can also be classified into fore-arc type [2,27], island arc type [2], and back-arc type [23,2]. Aiming at the aforementioned controversies, this study takes the Quedingbu-Yiluqu-Yibang segment of the Shigatse Ophiolite and mantle peridotites as research objects. By carrying out petrological, mineral chemical, and petrogeochemical analyses on these samples, the genesis of mantle peridotites is explored. Combined with previous research findings, the formation environment of the rocks is discussed, thereby providing new constraints on the formation and evolution of the Neo-Tethyan Ocean in the Qinghai-Tibet Plateau.

Suntrans: To Build a Leading International Platform for Mining & Energy Consulting and Translation Services in China

Dr. Lyu Guo graduated from China University of Geosciences (Beijing) with a doctorate degree in Mineralogy, Petrology, and Mineral Deposit Geology. During his doctoral studies, he studied at the University of Miami (USA) as a government-sponsored international student. Later, he conducted research on metallogenic regularity at the Postdoctoral Research Station of the School of Earth and Space Sciences, Peking University. After graduation, Dr. Lyu worked at BHP Billiton (the world’s largest mining company) and subsequently at the Overseas Mineral Strategy Research Office of the China Geological Survey (CGS). During this period, he participated in compiling the Guides to Mining Investment in Various Countries series and several works in the field of geology and mining. For many years, Dr. Lyu has continuously provided translation services for important conferences such as the China International Mining Congress, the Prospectors & Developers Association of Canada (PDAC), the China-ASEAN Mining Cooperation Forum, and the Iron Ore Forum, as well as for institutions including the Ministry of Natural Resources (formerly the Ministry of Land and Resources), the China Geological Survey, and the foreign aid training programs of the Ministry of Commerce. He has also provided translation services for presidential and ministerial-level dignitaries from many countries. His work has been covered by Chinese and foreign media, including China Central Television (CCTV), American Broadcasting Company (ABC), Uganda National Television (NT), Africa’s New Vision, Daily Monitor, Mirror, and China Land and Resources News. In addition, Dr. Lyu has organized and hosted a series of “International Mining Development Forums” and “International Translation Forums”.

Founded in 2008, Suntrans initially provided mining translation services for domestic enterprises. After 16 years of pioneering and development, its business scope now covers the entire mining industry chain, and it has grown into an international comprehensive mining enterprise serving clients at home and abroad. With its headquarters in Beijing, Suntrans has a branch in New York (USA) and offices in Uganda and Pakistan. Its cooperative enterprises are distributed across North America, South America, Africa, the Middle East, Eastern Europe, Western Europe, and Southeast Asia. In addition to cooperating with domestic and foreign enterprises, Suntrans also works with national government departments to provide high-quality mining-related services for foreign heads of state.

Since its establishment, Suntrans has successively provided high-quality translation services for domestic and foreign government departments and international organizations such as the Ministry of Land and Resources of China, the Development and Research Center of the China Geological Survey, the Ministry of Commerce of China, the National Development and Reform Commission (NDRC), the China Banking Regulatory Commission (CBRC), the U.S. Geological Survey, the Ministry of Finance of Canada, the Ministry of Health of Brazil, the Government of Papua New Guinea, the European Commission, and the Group of Twenty (G20); important conferences including the China International Mining Congress, the China-ASEAN Mining Congress, the Healthcare Information and Management Systems Society (HIMSS), the China (Beijing) International Fair for Trade in Services (CIFTIS), the China Import and Export Fair (Canton Fair), the Boao Forum for Asia (BFA), and the World Economic Forum Annual Meeting in Davos; and more than 1,000 enterprises and public institutions in over 60 countries worldwide. Up to now, the company has completed a total of over 1 billion words of translation in various fields and accumulated more than one million professional terms.
